Two pi and half sigma bonds are present in :

A

NO

B

CN

C

CO

D

`N_2`

Text Solution

Verified by Experts

The correct Answer is:
B
`Sigma_(1s^2) sigma_(1s^2) sigma_(2s^2) pi_(2px^2) pi_(2py^2) sigma_(2pz^1) ` (For CN)
Hence B.O is `(2 + 2 +1)/(2) = 2.5`
Out of which we have `2pi " and " 0.5 sigma ` bond
