Vedclass · Answer

(A) The reaction involves the replacement of a chlorine atom $(-Cl)$ by a hydroxyl group $(-OH)$ in $p-nitrochlorobenzene$.Since the $-NO_2$ group is a strong electron-withdrawing group,it activates the benzene ring towards nucleophilic attack at the ortho and para positions.This is a classic example of Nucleophilic Aromatic Substitution ($S_NAr$ mechanism),where the hydroxide ion $(OH^-)$ acts as a nucleophile and attacks the carbon atom attached to the chlorine,leading to the displacement of the chloride ion $(Cl^-)$.Therefore,the correct answer is Nucleophilic substitution.

The following reaction is:
$p-Nitrochlorobenzene + KOH \xrightarrow{\Delta} p-Nitrophenol + KCl$
