Question

The order of Cl-O bond energy in ClO^–,
ClO₂^–, ClO₃^–, ClO₄^– is

Easy

A

ClO^– > ClO₂^–> ClO₃^- > ClO₄^–
B

ClO₄^– > ClO₃^– > ClO₂^– > ClO^–
C

ClO₄^– > ClO₂^– > ClO₃^– > ClO^–
D

ClO₃^– > ClO– > ClO₂^– > ClO₄^–

Solution

Except in hypochlorite, all these anions are stabilised by resonance structures. Perchlorate ion has four canonical structures and is most stable.so bond order increases, then bond energy increases
