Bro don't misguide someone this video is not meant for revision of chemical bonding it's for beginners as for revision you can't prefer to watch 20 lectures and if u do so than forget about your selection

I WAS HAVING SAME DOUBT BUT NOW CLEARED IN L9 SIR SAID THAT CRITERIA IS USED BECAUSE WHEN SIDE ATOM ARE BIGGER IN SIZE THEY REPEL EACH OTHER THIS MEANS THIS CRITERIA SAYS WHEN REPULSION BETWEEN BONDS IS THERE BOND ANGLE IS MORE in this example bond angle will be more because repulsion due to size of side atom is less than e- e- repulsion so repulsion is more in NH3 irrespective of size of side atom

Sir plz ek esa video banao jis mein hum pata kar sake ki kis mein lone pair hai , kis mein vacant orbital , kis mein vacant d orbital h , kisme negetive charge and positive charge ko kya maanta hai lone pair ya electron ya vacant orbital sir plz es par alag se video banao bahut confusion doubt hota hai mujhe 😭😭😭😭😭😭😭😭😭😭😭😭😭😭🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
sir back bonding me agar jo bond banega vo pie h to aur atoms bhi to so many pi bonds banate h . for eg pcl5 me p forms f sigma bonds then why the bb bond cannot be considered s another pi bond
Bhai kyunki wo SP^2 hybridise hai jiske wajah se S ka ek e- P orbital mein hoga ( excitated state ) taki sp^2 hybridization bane aur ek p orbital mein 2 e- honge ( lone pair ) Ek baar try karo hybridization structure se
Sir at 28:40 you say agar pahle se bond ho aur phir naya bond bane to back bonding bolenge, is logic se CO mein backbonding honi chahiye instead of covalent bond kyunki usme do bonds already hai pahle se...so can someone explain this?
Bro carbon and oxygen shares it valence electron so C and oxygen form 3bonds then they form covalent bond. jyada acche se toh nhi bata paya mai so sorry.
1)2p -4d ..kaafi zada size difference hai...isliye vo nahi krta.. 2) Double bond pair -single bond pair ka repulsion zada hota hai single bond pair-single bond pair ke se...repulsion zada toh bond angle zada
Are bro carbon waha electron deficient hai mtlb incomplete hai aur flourine ke pass lone pair hai toh usko donate kr dega aur donate v 2p-2p mai ho rha hai jabki chlorine wale mai 2p-3p mai jis se iska back bonding achi nhi hai isliye wo jyada stable tha.😀👍

45:07if bong angles are compared by looking at the size of side atoms as sir told earlier...then the answer would be different
Bro the criterias are to be used in order
@@Mrrthe_ the criteria failed that is why I have a doubt in this
I WAS HAVING SAME DOUBT BUT NOW CLEARED IN L9 SIR SAID THAT CRITERIA IS USED BECAUSE WHEN SIDE ATOM ARE BIGGER IN SIZE THEY REPEL EACH OTHER THIS MEANS THIS CRITERIA SAYS WHEN REPULSION BETWEEN BONDS IS THERE BOND ANGLE IS MORE in this example bond angle will be more because repulsion due to size of side atom is less than e- e- repulsion so repulsion is more in NH3 irrespective of size of side atom
Sir, in 41:58 can we also say that EN of donor atom increases L to R, due to which donating will be lesser?
😂😂

2. Why bond angle inc if pie bond character is there 😞😓😭

1)2p -4d ..kaafi zada size difference hai...isliye vo nahi krta..
2) Double bond pair -single bond pair ka repulsion zada hota hai single bond pair-single bond pair ke se...repulsion zada toh bond angle zada

43:28 sir you said wrong .... F doesnt have vacant orbital thus it cannot involve in backbonding.. thus CCl3 is more stable
15 mins ago😯
Okay I completed this. Also, carbon me vacant orbital hai, fluorine me nai, fluorine ke pass lone pair. Isliye vo jyaada stable hai ccl3 se
