Which of the following undergoes nucleophilic substitution (hydrolysis) most easily when treated wit — Haloalkanes and Haloarenes Chemistry Question

💡 Solution & Explanation

The rate of nucleophilic aromatic substitution ($S_NAr$) increases dramatically with the number of electron-withdrawing groups (such as $-NO_2$) located at the ortho and para positions, as they effectively stabilize the intermediate carbanion.
