Postulates of Werner's Theory | Coordination Compounds Class 12 Chemistry @a2zpractical991

So, kids, today we were going to discuss Warner's theory which is Coordination chemistry is one of the most important fields in chemistry. People squared off against something Something in brackets Here in the square bracket But you must have seen some metals The scent in the boy's armpits and the hole of the fong. What do you say, what do you say, clean speak, children, if Has happened Inside the squib, this is metal, and this is it. It's legendary, it's real, this is the center metal, remember After that, why do the negatively charged anions go to the cathode? This is the parrot space of the lour. Here is the request Get away from these bonds The beginning of codination chemistry occurred and Warner's had explained all of this. Who explained this to Warner? So, Warner is called the father of coordination chemistry. If you don't understand this, it works something like this. Like a cyanide, two cyanides, that's fine Such cyanide ones that are anions, right? No, not its electrons to the central metal When sent into orbit, due to which there is one here Bonding occurs between a child and this same bonding is what we people coordinate as cordination bond. They say, and this entire explanation has been provided by our Varnar Baba. So that's why it's called the Warner Theory. Now pay close attention and see exactly what's in the Warner Theory So we will examine the postulates of Warner's theory, and we will first examine the initial postulate, which is yours Metal is something, as I showed you, metal possesses two types. There is one valence, a child, located exactly outside the square bracket of this. We say primary valences, and there is one inside square brackets. The anions inside that connect to the metal are what we call Alright, go and check it yourself. If you've studied coordination chemistry, that's great, alright, These are called primary valences, and these are called secondary valences. primary valences, no, if you, If you dissolve this in water, it becomes ionizable. It could come out, but the child who has secondary valences Primary valence is the ionizable valence. The point is, it might come out when you put it in water. The fluorides will be removed, and the secondary valence will remain. It's non-ionizable, okay? Remember two things. Let's keep going; now we see the children who are our primary valences. Isn't it so, that satisfy, meaning whatever your primary valences are Here there are three primary valencies, okay, three of them. Chlorite scan, tell me, child, what is this telling you? The plus the charge plus the metal you have It's a charge, whether it's your primary or your ionizable one. It is consistent with the identities; the diet satisfies. The given primary valence of the metal atom is that of Yes, this is the primary valence, isn't it, for metals? Satisfied, satisfied, what does it mean, like here If you remove three chloride ions, then why copper? Three positive charges will be applied, okay? So, whatever the uncharged... Three there is a child in primary valencies there Satisfy the valencies of the metal What exactly are you doing to my metal valences? Cutting, satisfying, this time metal paper plus 3 charge, due to which What is here attached to the iron with 3 chlorides? Alright, regarding your primary valency generally It will be, basically those are your anions themselves It will happen, those cuts will never happen, okay Because the more anions there are in it A positive charge of that magnitude will appear on the copper here, just like the 3 here, right? It's Cl3, so the copper has a +3 charge on top, right? What are the three anayans there, given, and what is your second one, The second one, your secondary valencies, which What will be the coordination number of the compound, meaning copper? What will be the coordination number here, and how much copper? It will create a bond with people, okay? So who is this? This shows your secondary balance, which is if it is non-ionizable, then the same as the secondary coordination sphere consists of entities which satisfy the secondary valences and are non-ionizable. Okay then This satisfies the secondary valences; now look here. Here, the secondary valences are six NH3 molecules. So, the coordination number here will become 6 due to this. And the child states this same 6 coordination number. Its geometry will be octahedral. Which geometry will it be? It will be octahedral geometry. And what exactly is octahedral geometry? due to the secondary balances.Does not contain any additional information or context. carries out and from that very moment a special arrangement It seems you're meeting Friedricha, that's right, this one The verse arrangement decides that this donkey is incompetent. It's telling this prepared pular that the number is 230. This is telling you about secondary valences. Secondary valences are non-ionizable. and secondary valences indicate the coordination number of the central metal atom or ion Because of which we decide the entire structures It will be octahedral, it will be tetrahedral, okay That is, the secondary balances have fixed spatial arrangements. around the central metal atom and describe the structures What makes structures? So this is all about the postulates of Warner's theory Warner didn't tell us the postulates Warner didn't tell us that actually Coordination compounds are such compounds To watch such interesting videos Don't ask me to follow up on the A to Z practicums See you in my next video, thank you
