Sulphur vapours exhibit some paramagnetic behaviour. Explain.

Text Solution

Verified by Experts

In the vapour state sulphur partly exists as `S_(2)` molecules similar to `O_(2)` molecules. Just like oxygen, sulphur molecule has also two unpaired electrons in the antibonding `pi^(**)`orbitals. Therefore, it exhibits paramagnetic character in the vapour state.
