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

Fluorine never acts as the central atom in polyatomic interhalogen compounds.

Account for the following : (i) IC l is more reactive than I_(2) . (ii) Fluorine never acts as the central atom in polyatomic interhalogen compounds. (iii) Halogens are strong oxidising agents.

How would you account for the following : (i) The electron gain enthalpy with negative sign is less for oxygen than that for sulphur. (ii) Phosphorus shows greater tandency for catenation than nitrogen. (iii) Fluorine never acts as the central atom in polyatomic interhalogen compounds.
