Vedclass · Answer

(C) The alkaline hydrolysis of an ester involves the nucleophilic attack of $OH^-$ on the carbonyl carbon. The rate of this reaction is increased by the presence of electron-withdrawing groups on the phenyl ring,as they make the carbonyl carbon more electrophilic and stabilize the transition state.Comparing the substituents on the phenyl ring:$1$. $-H$ (Phenyl acetate)$2$. $-Cl$ (p-Chlorophenyl acetate) - Electron-withdrawing by inductive effect $(-I)$$3$. $-NO_2$ (p-Nitrophenyl acetate) - Strong electron-withdrawing by both inductive $(-I)$ and resonance $(-M)$ effects$4$. $-OCH_3$ (p-Methoxyphenyl acetate) - Electron-donating by resonance $(+M)$The $-NO_2$ group is the strongest electron-withdrawing group among the given options. Therefore,$p$-Nitrophenyl acetate will be the most reactive towards alkaline hydrolysis.
