Sulphur is paramagnetic in the vapour state-why?

Text Solution

Verified by Experts

In the vapour state ( -1000 K) , sulphur mainly exists as `S_(2)` molecules. From the molecular orbital electronic configuration of `S_(2)` molecule, it becomes evident that the molecule (like `O_(2)` ) has two unpaired electrons in the antibonding `pi` -molecular orbitals. Hence, sulphur is paramagnetic in nature in the vapour state.

Paramagnetic species are-

`O_(2)^(+)`

`O_(2)^(-)`

`N_(2)^(+)`

`N_(2)^(-)`

Two liquids having vapour pressures p_1^0 and p_2^0 in pure state in the ratio of 2:1 are mixed in the motar ratio of 1:2. The ratio of their moles in the vapour state would be:

1:1

1:2

2:1

3:2
