Vedclass · Answer

(D) The $-NO_2$ group is a strong electron-withdrawing group due to its $-I$ and $-M$ effects. In $2,4-$dinitrochlorobenzene,the $-NO_2$ groups are present at the ortho and para positions relative to the chlorine atom. These groups withdraw electron density from the ring,specifically stabilizing the carbanion intermediate formed during nucleophilic aromatic substitution. This makes the $C-Cl$ bond more susceptible to nucleophilic attack,thus facilitating the replacement of the chlorine atom under milder conditions.

Replacement of $Cl$ of chlorobenzene to give phenol requires drastic conditions,but chlorine of $2,4-$dinitrochlorobenzene is readily replaced because:
