Q. Assertion : Replacement of $-C l$ group by $-O H$ in chlorobenzene is easier if nitro group is present in the ring.
Reason: Nitro group leads to strengthening o f the $C—Cl $ bond in chlorobenzene.

Haloalkanes and Haloarenes

Solution:

Nitro group is an electron withdrawing group which leads to weakening of $C—Cl$ bond, hence making it easier to replace the $-Cl$ group.
