Sulphur exhibits +4 as well as +6 oxidation states but oxygen exhibits none-explain.

Text Solution

Verified by Experts

Sulphur has vacant d -orbitals. Transfer of electrons take place from its 3p - and 3s -orbitals resulting in 4 and 6 unpaired electrons. Hence, sulphur exhibits +4 as well as +6 oxidation states.
On the other hand, oxygen has no vacant d -orbital and thus transfer of electrons is not possible. So, oxygen does not exhibit +4 and +6 oxidation states.
