Question

Amongst the following the number of oxide(s) which are paramagnetic in nature is Na 2 O , KO 2 , NO 2 , &#160; N 2 O , ClO 2 , NO , SO 2 , Cl 2 O

Aicharya · Accepted Answer

The magnetic properties of a substance can be determined by examining its electron configuration: If it has unpaired electrons, then the substance is paramagnetic and if all electrons are paired, the substance is then diamagnetic.
${KO}_{2}$ is potassium superoxide. There is one unpaired electron in anti-bonding molecular orbital of superoxide. Potassium superoxide is paramagnetic due to the presence of unpaired electron.
${NO}_{2}, {ClO}_{2}, NO$ are odd electron species. Hence, they are paramagnetic.
The other are monoxide and dioxide contain paired electrons, so they will show diamagnetic behaviour.
