Why fluorine never acts as the central atom in polyatomic interhalogen compounds?

Text Solution

Verified by Experts

The correct Answer is:
The reasons are :
(i)F being smaller cannot accommodate larger sized other halogen atoms around it.
(ii)Due to the absence of d-orbitals, F does not show positive oxidation states of `+3,+5` or `+7` needed for the formation of polyatomic interhalogen compounds.
