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.

Text Solution

Verified by Experts

(i) `IC l` is more reactive than `I_(2)` : It is because `I-Cl` bond is comparatively weaker than `I-I` Bond.
(ii) Fluorine never acts as the central atom in polyatomic interhalogen compounds because of its high electronegativity and high ioonisation energy.
(iii) Halogens are strong oxidizing agents because they are only one electron less to attain noble gas configuration. Thus, they easily accept electrons to form halide ions.
