Among the following, the correct order of energies of molecular orbitals of N2 is-

1. (π2py)<(σ2pz)<(π*2px)(π*2py)

2. (π2py)>(σ2pz)>(π*2px)(π*2py)

3. (π2py)<(σ2pz) (π*2px)(π*2py)

4. (π2py)>(σ2pz)<(π*2px)(π*2py)

 

Hint: Energy of  σ2pz molecular orbital is more than π*2pxπ*2py molecular orbital.

Explanation:

Step 1: The MOT diagram for N2 is as follows:

draw the molecular orbital diagram of n2 also find its bond order and  magnetic character - Chemistry - TopperLearning.com | 4s4p942zz

Step 2:

So According to the above molecular orbital diagram

The order of energies of molecular orbitals of N2 is as follows:

(π2py)<(σ2pz)<(π*2px)(π*2py)
