Vedclass · Answer

(D) Nucleophilic aromatic substitution is facilitated by electron-withdrawing groups $(EWG)$ on the benzene ring,which stabilize the intermediate carbanion (Meisenheimer complex). Conversely,electron-donating groups $(EDG)$ decrease the reactivity towards nucleophilic attack. Let's analyze the substituents: $I$: $-OCH_3$ is a strong electron-donating group (via resonance). $II$: $-CH_3$ is a weak electron-donating group (via hyperconjugation). $III$: Benzene (no substituent). $IV$: $-CF_3$ is a strong electron-withdrawing group (via inductive effect). Therefore,the reactivity order is $IV > III > II > I$.
