Solution

The correct option is B 2

Let's think about the question.

First, we have to find out the bond order of MOT.

As we know how to draw MOT of N2.

Because for bonding, we only need valance electrons

Now, bond order = 12 [Number of bonding electrons - Number of anti-bonding electrons]
=12[82]=3

Therefore, there will be three bonds between two nitrogen atoms.

Out of these three bonds, 2 bonds will be π bonds (formed by 2px & 2py) and one will σ bond (formed by 2pz).

The number of bonds in nitrogen molecule is 2.

Answer 2 bonds.
