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

Text Solution

Verified by Experts

Fluorine never acts as the central atom is polyatomic interhalogen compounds, electronic configuration of fluorine is `2s^(2)2p^(5)` and due to absence of vacant d-orbital, fluorine cannot expand its coordination number more than 1(one).
