Q. Assertion (A) $X-X'$ bond in interhalogens is weaker than $X-X$ bond in halogens.
Reason (R) Interhalogen compounds are more reactive than halogens (except fluorine).

The p-Block Elements - Part2

Solution:

Interhalogen compounds are more reactive than halogens (except fluorine). This is because $X-X'$ bond in interhalogens is weaker than $X-X$ bond.
All these undergo hydrolysis giving halide ion derived from the smaller halogen and a hypohalite (when $X X'$ ), halite (when $X X_{3}'$ ), halate (when $X X_{5}'$ ) and perhalate (when $X X_{7}'$ ) anion derived from the larger halogen.
$X X'+ H _{2} O \longrightarrow H X^{\prime}+ HO X$
