Number of paramagnetic molecules from the following are:
$C N^{-}, N O, O_{2}^{2 -}, O_{2}, N O_{2}, O_{2}^{-}, B_{2}, C_{2}, F_{2}^{-}$

Open in App

Solution

The number of paramagnetic molecules/ions are six. These include $N O, O_{2}, N O_{2}, O_{2}^{-}, B_{2}, F_{2}^{-}$

Paramagnetic molecules have one or more unpaired electrons. The numbers in bracket represent the number of unpaired electrons.

The number of diamagnetic molecules/ions are three. These include $C N^{-}, O_{2}^{2 -}, C_{2}$

In diamagnetic molecules, all electrons are paired.
