Guys, I'm just thinking about how Nitrogen makes two bonds if it has 3 electrons in 2p orbital. I made a judgement that one electron from 2s orbital will transfer to one of 2p orbitals then there are two 2p orbitals which can make a bond? Is this correct or there is other mechanism?

Nitrogen actually makes 3 bonds. 2 p-electrons form a sigma-bond and 2 x 2 p-electrons form 2 pi-bonds. The s-electrons are not binding.

Yeah but what's happening in the case of Nitric oxide?
 
In nitric oxide, you have one additional electron, so you will get a 3-electron pi bond which is about half as strong as a 2 electron pi bond. So you will get an overall bond order of 2.5.

Can you just elaborate. Extra electron means tha nitrogen gains a electron then it makes a bond?
 
No, I meant that in nitric oxide you have one more valence electron as compared to dinitrogen.

The extra electron populates an anti-binding pi orbital. It belongs to the molecule and not to nitrogen or oxygen only.

Ohk to understand this concept should I first understand MOT
