Which of the following species is paramagnetic ?

A

`O_2^(2-)`

B

`NO`

C

`CO`

D

`CN^-`

Text Solution

Verified by Experts

The correct Answer is:
B
The molecular orbital configuration of NO is
`KK(sigma2s)^2(overset***sigma2s)^2(sigma2p_x)^2 (pi2p_x)^2 (pi2p_y)^2 (pi2p_z)^2 (overset***pi2p_y)^1`
So, NO is paramagnetic because it contains one unpaired electron.
