Which one of the following molecules is paramagnetic?

A$$N_2$$
B$$NO$$
Correct Answer
C$$CO$$
D$$O_3$$

Solution

A molecule with one or more unpaired electrons is paramagnetic or odd electron system is paramagnetic. $$NO$$ has 15 electrons and has a bond order of $$2.5$$ and has 1 unpaired electron in $$\pi^*$$ antibonding orbitals. So, $$NO$$ is a paramagnetic molecule.
