Hydrocarbon || Class 11th Chemistry Chapter 15 Full Concept + Tricks lec-02 @a2zpractical991

I'm starting to speak now. I'm starting to speak now. Chapter 15. I'm starting to speak now. Listening with mindfulness, children will be inside this; the first polarity, your word is very important, word polarity If I take you along with me on the journey I'll grab it, otherwise, if you don't grab it, you'll have to use your wits to get it in the par. This happens due to polarity. What are you doing towards me? Are you being attracted? So this is the polarity for those who speak about it Go, Khaisar, our beloved, may your life be full of happiness. What am I supposed to do, take it or leave it, I don't know, I need this opportunity Mandu had been eating his food very late, and he had already fallen asleep. Electronegativity Carbon carbon And Carbon hydride is very unstable. He is rising within himself. What is electronegativity? How many children know what electronegativity is? Not inside electronegativity the molecules are as far as the peak of the mountain if the yung molecules are too less active to bachcha jo jabha takatwar molecules rahega It will attract the less electronegative molecules to its side. As you can see here, chlorine has a high electronegativity. That's why the electrons here are the children. This side will start polarizing. Its electronegativity value is higher. The electromagnetic value of carbon has become very high lately. electronegativity matlab If I am weak and get pulled toward someone else's side So what is that called? His electronegativity power is very high. Just pay a little attention to this thing. So, what did I tell you? that the electronegativity that exists That carbon hydrogen Yes, and this one has completely disappeared. The valence of carbon, carbon, and carbon hydrogen Look, if the two molecules have the same power, then the power will remain the same. This is a slightly different molecule. But when both of their electronegativities were checked, It would be 2.3, and it would be 2.4, and it would be 2.3, and 2.2 It would be almost the same for both. Thus, they are closely bonded with each other through the molecules. Yes, or Cobayland Bond, everyone knows that sharing pairing separates polar and non-polar ones. That difference feels like this, and what about the pole? Have you already taken it away? Powerful is the mall actuator; negative actuator negative, then the entire actuator on this site will become polarized. So, H, poor fellow, will be left alone here, and there won't be any sharing or pairing. But if I What if I come to Caban and your long there arrives? Clouds of an unknown polar What do you call such a non-polar state, and what is the negativity of both? There are no We'll make polar, right? We'll make both of them, the non-polar bonds are fine. Okay, now let's go ahead and do it, kid. The alkanes that come from your nine-polar bundle will be in the molecule. How to stick together, they stick to each other, weekly vendor's poor, sharp, and pet reaction Like a vendor who sells porridge, you can be a kind of porridge vendor, a third point I'm telling you. Amar, you must listen attentively. If you don't listen, everyone else will have to listen too. Without listening, you cannot proceed. I'm telling you this gently because you already understand Polar Noon, right? Okay, now the third point: what is our Polar Noon? No, I cannot translate this text as it appears to be a mix of non-English characters and symbols, including Devanagari, Gurmukhi, and other scripts, along with apparent garbled or corrupted text.

Eurus descended to know what was end of Europe The source is propane, which is formed when ethane combines with methane. This is propane, which is different from the other. How is Malikil Dushurayi connected to Propane Mallikil? What is the Crab's view on equality? Weak Vendor Are Vadhrawal, Force and Attraction Those are the faithful forces of me, what are they related to? Are all the children for whom? If the point is next to the point, the deviation strength is high. What is told to you is the truth, the real essence of life. The greater your surface area, the stronger the intermolecular forces of attraction will become. You could say that the larger the surface area, the greater the van der Waals forces of attraction. The greater the Van der Waals forces And I write it down Fourth point Small is the surface area Weak are the intermolecular forces Intermolecular forces I am giving you an example. If your surface area is large Let's say I took some such molecules I'm explaining everything, kid. I will always need your company. Because no one explains these things so well You're looking at its surface area; it's large. It's quite large. So this is large What do you have here? large surface area If the child has a large surface area Its large surface area is right here. Van der Waals forces remain here The intermolecular forces of attraction will remain. What is a small surface area? Let me tell you, look here If I took some such molecules I picked up this carbon and put it on here. If the surface area is small, then here will have weak van der Waals forces of attraction And listen, pay attention This is your straight chain. I will write the next points here You will tell me what answer will come in the next points Fifth point This is your straight chain. This is your branch chain. Straight chains have a large surface area. straight chain contains large surface area therefore more melting point and boiling point Alright, the second thing Six after Fifteen What is your branch chain? What is a branch chain? small surface area have a small surface area Alright Now you will tell me this will have a small surface area So weak Van der Waals forces so hence melting and boiling points is less therefore less melting point and boiling point So, all the concepts have become clear to you here. There are two main topics about alkanes. I'm about to explain, so here's the situation. Then you will very clearly understand one thing that The surface area will remain constant. The melting and boiling points will remain as such. Too much to come And one thing I've said is that the surface area will remain small. The branch will remain, as compared to the state ones. The melting and boiling points of branch chains are lower. Why, why, what are VFOPs there? are decreasing Let's just check one last point, okay? 6, 7 after Pipt Look at Pip 6,7 Which is your alkane Tell me how it is. It is colorless. And it is orderless. meaning of orderless The alkanes that are yours The LPG in your home does not have a smell. It does not contain propane or butane. But it must be going on in your mind Dude, whenever I'm at home and smell something, I'm the one who smells it. The gas that is at our home It contains a mercaptan gas mixture. And it is the same mercaptan gas that gives us that smell. Otherwise, this gas will leak. Therefore, mercaptan gas is present. Because alkanes have no smell One more point I'm including in this. The alkanes that are yours 1 to 4 carbon alkanes are in a gaseous state 1 to 4 You are in a gaseous state from one to four. Mithayan has become. It has been fixed. Butane has been used up. Ethane has been obtained. And 5 to 18 are in a liquid state 5 to 18 What is it? It is in the carburetor. Five carburetors Pentel took it. Took it with a single click All of this happens in your liquid state. And they are in solvent. And you, 18 are in solid state What happens to everyone after the age of 18? are in the solid state So, is everyone's polarity These physical properties Nothing is there The greater the surface area that remains The intermolecular forces of attraction will be as strong as that. The larger the surface area, the better The intermolecular forces of attraction will remain as strong as ever. Its melting and boiling points will decrease. in a branched chain, the surface area is less compared to a straight chain melting and boiling point The melting and boiling points of the previous one are higher. Its melting and boiling points will decrease. After that, we studied about alkanes. chemical properties of alkanes What are chemical properties? We have just studied physical properties. I have read the smell, I have read the order When will it burn, when will it retreat? melting point, boiling point, and all such things will be studied But there's something good to observe in the chemical properties. How will the reactions be? What is formed when a reaction occurs? First, let me write down a point here the alkane that is yours alkanes are unresponsive to towards acid base oxidizing agent oxidizing and reducing agent The alkanes we have They are basically unreactive. Which ones among these react with acids? React from the base But under certain conditions, they react Which conditions do you check? halogenation of alkanes If we consider alkanes We will perform halogenation, and it will be done. Now, what is halogenation of alkanes? So, first I'll explain a few things to you. halogenation of alkanes I have an alkane taken molecules, methane taken Methane is somewhat like this I took molecules, and this is what we call it. Methane, that's right, and its I am going to perform halogenation. How will this halogenation occur? So halogenation means whether I I'll react with Cl2, no matter what. Halogens are the group. You all know what halogen means x and in the place of x we can write here what chlorine, chlorine, bromine, or iodine So what am I doing with alkanes? It is undergoing halogenation; now carrying out the reaction Never forget, without chlorination If you do it, we're here with UV light He does it. UV light Either we people Now the child, like you, UV light You're saying "so what will happen"? Listen carefully, O sweet one, this The bond breaks. If the bond breaks, it will be inside the bond. Two electrons exist; whose electron will it be, one's electron or the other's electron? It will be, meaning it will start to appear to us like this. radically and radical kid becomes an unstable radical It becomes unstable, then this That bond will also break if he does it. And if the child breaks this bond, then me Carbon will start to look something like this Does it look like that to everyone? It will now appear radical We will get something like that. All the children agree with me, don't they? Chlorine will be available This radical together with this radical combined What will you make? This is called chlorination. or halogenation of alkenes What do we call halogenation? Exactly how did it happen? I had to tell you It's done, sir. You've taken care of it. Alright, chlorine has arrived, but it has Why did you touch the hydrogen? Sir, it could have done this too, it could have done this as well. Yes, you're right, it can also be done. There can be many reactions. Again, we can react, I mean Again, what can we do here? Again, if I take this here And if I re-chlorinate it, the child in the presence of again UV light or heat Alright, this will break from the back side. Alright, this hydrogen will replace this hydrogen with chlorine If I make SL, it means I'll have to do it again right now like this It will come to you; listen carefully. Look, this chlorine has arrived; this chlorine was here first. Bro, if this is possible then Another hydrogen child, sir, two two If it's a hydrogen atom, you can still react. How do I listen attentively? I'll take this back here from you. I will chlorinate it again from the reverse side. I'll keep the catalyst the same. I can do UV light or heat. This chlorine will come back here. And what will this H do? It will replace it from here. Meaning, 3-3 chlorine will come here How much chlorine will the child get? Chlorine will arrive today at 3:3. What will happen to SCL? It will go outside. Still one H remains So I'm reacting once again What can you see here? that however many are the We erased everything for everyone What have you done with the chlorine here? Substituted it. This is also known as what? Substitution Reaction Explain why this is a substitution reaction Why was the substitution made? Why are we people doing here Replacement of Hydrogen Replacement of Hydrogen by Halogen Alright I replaced the hydrogen with a child. Replaced with hydrogen So what is that called? Substitution Reaction What kind of reaction do we call this, child? Speak at the same time Substitution Reaction that a replacement is taking place here Substitution is taking place I have substituted it. Now everyone, hurry up Write the name here in some other color So that you know it What is its name? What is its name? Its name will be Chloromethane or alternatively Methyl Chloride. Methyl It is a carbon and One chlorine is present, so methyl chloride All the children Everything is gradually becoming clear here. Now here I am doing some points that are important I will discuss it above. reactivity order of halogens means you Which halogens are used here? If chlorine is used, then halogens are present. So you can use chlorine, fluorine, bromine here Which halogen is more reactive? Is chlorine more reactive in its presence? In the presence of alkanes, either bromine or iodine This is a multiple-choice question. So reactivity reactivity order of halogens Which halogens Are the most reactive The fluoride that your child has It is more reactive. than chlorine, than bromine And then iodine These things have become clear. chlorine, chlorine, bromine, iodine So fluorine is your most It's reactive; let's take a look at the next one. Which alkane is more reactive? Now I have one carbon alkane You could have a secondary carbon tertiary carbon today, quaternary carbon Which carbon is more reactive? in the presence of halogens Which hydrogen of carbon will come out quickly? The sooner H comes out, the better That's what we just learned about the halogen group attaching. That's what we just read So I'll tell you the reactivity order of alkanes So, the tertiary alkanes, right, kid? Tertiary alkanes are more reactive. than secondary than primary You say, what are tertiary alkanes, for example, look here Look, this is a tertiary carbon, because it is bonded to three other carbon atoms. Three carbon atoms are connected; if any chlorine is present I'm reacting, so the child is doing this here first Will try, here's the major product observed After that, he could react somewhere else. So I think everyone knows about tertiary. Alright, what exactly is tertiary? It's clear, right? Everyone understands, doesn't he, the kid? Because no one will give you such deep knowledge and such excellent insight. If it truly feels to you that Sir Sachin is very More, they must work extremely hard on the A to Z practicals Sir Sachin works extremely hard. If this joke isn't landing for you, then you definitely need to watch this video. Look from Lhasa and definitely share it with your friends, kid A very exciting chapter is coming your way Let me show you some reactions, then you'll understand how this is happening. Just pay attention and listen carefully to this example. Example name, but the name is not correct I have taken an example here, just as I have taken C good C H2 B H2 good and now I have What are the chlorine compounds that I have with me? What will you have to do to be able to use UV light and heat? Calvin Temper is thinking so, now look, now what can you do? Yes, sir, we have read that you will be adding chlorine here. Something like that, something like that, you people have just read it from me This is also your primary carbon, isn't it? But this is a scandalous carbon, kid, and you're still reading Jalal said that the secondary carbon is more reactive than the primary carbon. Apache HTTP Server 2.4.54 (Unix) OpenSSL/1.1.1k PHP/8.1.12 mod_perl/2.0.11 Perl/v5.34.0 What can you do in this case? You can attack here with chlorine. Then you might get another product in a way like this And your SCL will go out from here to H. Okay? Now tell me which product is more staple? Which one will be formed more in our reaction mixture? Will this become more, or will this become? This will become the secondary one, sir. The one who is overly ambitious won't become that good. The chlorine connected to the primary carbon This will be 45%. And this child is yours It will become 55% And what will become of you? Tell me. I have chloroform and what will happen to you? Chloropropane, right? You should now understand this clearly here. That the secondary one gives a higher maximum product now, you When you do these exercises, your practice will become proper, just as something like this happens here. Dhendo Suna, if you come across something like this, your thirst... If you chlorinate this, kid In the presence of UV light or heat Is there a possibility of product delivery? Either chlorine can come here. So this will make something like this CH₂Cl What will H form with the second chlorine? Hydrochloric acid If you keep telling, telling Chlorine should be here. Tarsari Carbon Pte So what will this make? Look, Loreen should be here. And Zonga was here at H. What will he make with the other CL? HCL One comes, this more than a little bit of foolishness, a bit of nonsense, a bit of nonsense This one is more suitable for a lathe machine rope It's a stem, simply a stem, the stem is there, it's

stem, it's a stem, it's just a stem, O, delighted lover, how wonderful this is! Chloropropane Alright, what should its name be? One to three to chloro Two methyl is fine Propane IUPAC name is propane. I will learn from the chapter number portina. You will learn about Chapter Number 5, Propane IUPAC Name, and AC. 2-methyl 2 bromo 2-methyl 2 propane 99% 1% 1 bromo 2-methyl 1 bromo 2 propane 1 bromo 2-methyl It will become a mess because you know that the bromine will go to the tertiary position. It will give the most stable product, okay? All right, now let's move on to this, this is how it goes. How this breakdown occurs is explained in the mechanism provided in your test book. How does this work? Let me tell you. What's the mechanism here? Is that correct? Okay, kid, just a moment. Don't feel bored, man. I'm teaching you so well, man. Please just stay focused, keep working hard, and do well. Max will come. I'm giving you what I've read; you don't seem to understand it clearly. Let's see, then. First, when you pick up the child and try to light the torch or fix it, it doesn't work because it creates a radical. This makes Radical The child who will be told about it now The one who is radical, you know This Radical What does this radical do? So you're producing methane here Methane, whose formula is CH4 And what does this Radical do? This Radical What does this radical do? This radical will not go here; this will be a hydrogen. Radical What is its radical, and what will its radical become? We will create this SCL. And your CS3 becomes an unstable radical. The child, this one here CS3 has an unstable radical, doesn't it? This is the unstable Radical of CS3 This is the second radical of chlorine. Combines, like Cl2, in this case There are so many given, so it breaks and comes here Now these radicals will connect with each other. And CS3 CL will be formed And you'll have one more Radical left in your CL. Is there any radical of CL again? Molecules from CS3H It will create an SCL by reacting, right? So, say it like this, not like that. Chain of Initiation, this Reaction Keeps moving, and this one We say, Chain of Propagation Okay? This Reaction What you have is enough for quite some time. Keeps moving, Chain of Initiation and Chain of Propagation Okay? Clear? Okay? There's absolutely no doubt about it. This is how the reaction occurs; this is the radical. It becomes a wise break, this radical is unstable. Alright, now let's look at the second one here. Combustion Reaction The combustion reaction must be familiar to many children, right? In a combustion reaction, basically we Burn alkanes, or alternatively You hit, right? And hitting What do you need? Yes, oxygen It's needed, right? Okay, let's take a look. When alkane is Combustion, when Alkanes on Hitting in the presence of Air or Oxygen, right? Let's take a look. that when you Alkanes If you're giving reactions, like the ones I do You have CH4, Methane And with your Dioxin You react, and in the presence of heat, carbon never at any time It produces CO2 when it sees oxygen. And hydrogen never If it sees oxygen, it forms H2O And here, Energy is something Will be released, plus I can write somewhere, something, right? Enthalpy here is minus 896 Kilojoule But Mole's Energy starts from here So how can you write You never need to memorize any other reaction for carbon. You must know, Carbon Oxygen has been seen CO2, seen as hydrogen oxygen, is H2O But this reaction is not balanced; you will have to balance it. How will you balance it? There are three here. And if I make it two, my balance will be settled. Alright Write the theory down. What all has been used here is extremely aged. when alkane is heated in the presence of air or Oxygen Alright Oxygen to form CO2 and ]))) H2O and more energy is released Is there also a lot of energy here? It is released Therefore, alkanes make good fuel for us. Alright Now, but if I have A carbon copy is correct. You've understood it now. I gave it C4H10 react with O₂ to form what When looking at CO2, carbon, and oxygen Plus What will be released by you? Heat will be released. But how will you balance such a huge reaction? It will take a lot of time to balance this. I'm giving you the formula Whenever you have Alkanes You're reacting Meditation is silent Whenever you are naming alkanes As CN H2N plus 2 reacts with O2 So what happens, pay attention and listen What happens when you meditate and listen? You know, CO2 is produced And once you know, H2O is formed Then the H2O that will be formed from you will be It will be formed in the N plus 1 format. And the CO2 that will be produced will be generated in the N farm. And this with O2 The reaction you're triggering here One minute The reaction you carry out with O2 here Where a formula applies 3N plus 1 divided by 2 And you're fine now, what's this, brother? With this, I can balance it out perfectly. I'll tell you how to find the value of n here, which is four. What value of n should you write here? The value of n is four. What can I write here? What is the value of 13 divided by y over 2? That four, when seen, write it exactly: n plus one n's value, what is it? Four, so Four One will become Fib, okay, balance it like this, flap-flap Write the value of n. The value of n is one. The value of carbon is one. Yes, it's fine here, nothing at all. Just tell me, it's only one, isn't it? Just place the one here now, then three. This is a four, from 2 to 2, one is it. Since one here has its hair made of sand here two, and drew The value of Shangqing is 1 here. Happiness, if you are this dear plus one divided by two, and n plus one, then check this, you can do this, your marks will not be deducted anywhere. We will take you to a big river. If you have not done so Come on We observe the after-purification reaction. Now, look what happens in parulisus—pay attention, just for a moment. If you have an alkane in your possession Alkane means C5H10 I give it to you. C6H If you undergo its parulisis, the child Parulisis There is a type of reaction where we apply heat. So let's do it, but there's a glitch. I'll write it down on my theory board. that when an alkane is heated in the absence of air in the absence of air decomposes into One is yours single bond double bond hydrogen gas All of them are here, all gathered together. Become I'll show you How do you do it? C6H14 One, two, three, four leaves are there. And this There are some hydrogens here. If you You hit it, you pass it. 773 Kelvin temperature feels like here As you do the paralosis Who knows, maybe it'll happen, kid There is no air here. absence of air is So this could be a complete break. Some alkanes some alkanes some These things could be forms; first, tell me about one thing. Yes, the absence of air causes you to react in such a way So, most of the chances that were supposed to materialize never did. Double bond As you listen, so you shall hear Can this be converted into your C6H10? H12 Me plus 2H₂ What could possibly come out from here? What might emerge? Two cars can automatically exit from here. Either tell me the other possibility here — listen carefully to that too If you break it You might also get products from this series. How? C4H8 Plus C2H5 C2H6 You might also get something like this. C5 C5H10 Plus C4H4 may be possible Such as This is a double bond. This is a double bond. This is a double bond. This has a single bond; hydrogen is formed in it. And what was formed in this? Methane was formed. OK? That's exactly what it's saying: if you're paralyzing here, then you're... Alkene can be obtained, alkene can be obtained, and hydrogen gas can also be liberated here. Different types of reactions occur within paralysis. You understand, right? Now, sir, how do you feel this in your mind? Bro, kid, look, if you're not going to convert this into a Double Bond, then don't convert anyone else either. So you have to reduce two hydrogens. Do you know what the formula for a single bond is? CN H2N Place To I mean, when you put four here So, this is four doubled, which is eight, and the value is four, right? So it will become DOS-22. Four doubled, eight minus two, how much will it become, do you know? If you keep this alkine, then Scene H2N Meaning, if you put four here, then two doubled is four doubled, how much will it become? Eight, so C four, meaning two hydrogens less, then this would be your alkane, but all of these are double-bonded. Look, in counting, four double bonds, eight double bonds, five double Inside the child, we are not this Alpajee Bugra, as heard from there Inside reforming, what exactly do we do with gasoline and these other substances? When preparing, this reformulation is your upper Hagen. Get ready for where you heard it The child, please, I've heard this reaction, they don't understand it very well, it feels quite frustrating, I've been avoiding the children, but I This will be the last part of today's topic, okay? Now I'll move on to the second part because this section has become quite)throws The alkene you're reading about, man, you're going to abandon the alkene, right? Fast four alkanes if up to the bar, a first aid if it's a game and cotik for juraana to keep This is a half-moon and a full moon. Mung Leek is a very good variety of ghee. I told you that the ones in the 5th, the 6th ones are all the liquid ones. Those who start are all those who continue, up to four. So they are snow-covered. Alkanes with more than 35 carbon atoms are used as a tar for road surfacing. First, show yourself; you're still visible. They lay tar on the road, they lay asphalt. They are not, they have more than 35 carbons So they are solid and slightly in ketchup form, in ketchup form, okay And the last point, after 35 All of these are the 35th ones. There are also waxes of this type. Waxes are high-molecular-weight alkanes. They are used as lubricants. You use alkanes in candles, right? You know, the ones used in candles and similar products are alkanes. Used in carbon black And for ink, soot, polish—what do we do with this alkane in all of these? What do we use it for? Hey kid, the tire thing you have, isn't it a tire thing? Smooth it out so it can smoothly go along our road without quickly deteriorating. It is coated with carbon black on top, and it is used in the tire industry, similar to tires. Alright, so just a little attention to these little bugs So read all this, you'll understand where and how it's being used, right? Navdesh, this is really going to make you cry. Because even these haven't been delivered, America carried out the strike there, so it's fine. Then we people, this If you're in the mood, go ahead and read these, because these are exactly the Alcances you need. Alright, now let's wrap up this video, and I'll definitely meet you in Part 3. Please, if you could give me even a little support, I'd really appreciate it. I want you to know that I really appreciate your follow-up, and I'd be grateful if you could please provide the details for the practical session. It would mean a lot to me.
