Which of the following molecule is paramagnetic?

A

`N_2`

B

`O_3`

C

`CO`

D

`NO`

Text Solution

Verified by Experts

The correct Answer is:
D
As per M.O.T.,
`N_2` (14 electron) all are paired electrons, hence diamagnetic
`N_2implies sigma1s^2 lt overset(**)sigma1s^2 ltsigma2s^2lt overset(**)sigma2s^2ltpi2Px^2=pi2Py^2 lt sigma2Pz^2`
`O_3` has 24 electron and it diamagnetic
