MOT
bruh, here we took N2 which has like 14e. so in MOT, for total e < 14, we consider or believe that pi 2px and pi 2py have lower energy than sigma 2pz so like my doubt is when we fill the electrons, we follow the hund's rule and aufbau principle, so like if a molecule has 10 electrons, as per what i have learnt is that when we start filling, we fill the lower energy orbitals first but since we have only 10 electrona, pi 2px and pi 2py will get occupied first so this means that pi bond is established before sigma, how?
or am i misinterpreting the ENTIRE MOT

Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.wait. never thought of that 💀
but its clear pi bond is established before sigma. pi bond is established but it will break (as it is stable but has less orbital overlapping region) until sigma bond is formed so pi bond will definitely form but without sigma bond it wont exist.. Like, who said a molecule with only pi bond is never formed. It is formed, but wont last!
disclaimer - its my understanding and im a 10th grade student so dont expect much
nahin samjha sir, i mean thoda bahut samjha but pura nahi
thanks anyways 😆
sir lecture link please 🥺
why does he sound alot like satya sir 😭🙏🏻
satya sir!!!!!
this is Aswin :) he used to make BYJUs videos
sir aap, satya sir and aswin sir
sab dost ho kya? like Homies!?
satya sir's cousin brother fr 😭🙏🏻 🔥

A better answer to this would be that bonds don't form in an "order"
All the molecular orbitals' order signifies is their energy level
Which in this case is affected by a phenomenon called "s-p mixing"
Saying pi bonds form after sigma bonds is the same as saying pi bonds are higher in terms of energy than sigma bonds which indeed is generally true but not always true
I can go on explaining the causes of s-p mixing and all if you want but that's only if you're interested
Sidenote, I recently taught this to first years at my college as a part of some help sessions I'm taking for their chemistry course:)
If you want I can share the link as well and if @iTeachChem allows
Sir bhej sakta hun kya links aise?
Like it kind of falls under self promotion that's why asking
so what you're saying that
electrons fill in an order but bonds dont form in an order.
why? electrons se hi to bonds bante hai, jis order me electron fill ho raha, usi order me to bond ban na chaiye
yes bhai please!! 🙏🏻
The point is that saying sigma bonds always form before pi bonds essentially puts a condition that sigma bonds are always energetically lower (in terms of their bonding molecular orbital) than a corresponding pi set
Which is not always true
As we see in the case of B2, C2, N2
These are the classic ones but not the only ones
You see such weird behaviour in CO as well if I'm not remembering incorrectly
Yes
I don't wanna type it out actually 😭
I have a video on that
If sir permits, then I'll put it here

Of course bro.
Self promotion me kya problem ahi
