The correct option is
D Explanation of the correct option:
D.
- A compound is diamagnetic if all its electrons are paired and paramagnetic if any of its electrons are unpaired.
- Nitric oxide contains an unpaired electron(odd electron), because of which is paramagnetic.
- The electronic configuration of according to MOT becomes
The bond order of is and it has one unpaired electron. Thus, it is paramagnetic in nature.
Explanation of incorrect options:
(A) In ozone all electrons are paired, so is diamagnetic.

(B) In Nitrogen there are no unpaired electrons, so is called diamagnetic.
- The electronic configuration of according to MOT is:
(C) All of the electrons are paired in carbon monoxide , so is known as diamagnetic.
- The electronic configuration of according to MOT is:
Hence, the correct option D i.e. is paramagnetic.
