Though nitrogen exhibits +5 oxidation state it does not form pentahalide. Give reason.

Text Solution

Verified by Experts

Nitrogen having n = 2 , possesses only s and p orbitals. It does not have d orbitals, hence, it cannot expand its covalence beyond four. It is for this reason, nitrogen does not form pentahalide though it exhibits +5 oxidation state.
