Question
The Dow Process converts chlorobenzene to phenol using aqueous $NaOH$. Because the $C-Cl$ bond is stabilized by resonance, what drastic conditions are required for this SNAr reaction?
Answer: D
💡 Solution & Explanation
Because unactivated aryl halides possess partial double-bond character in their $C-X$ bonds, standard nucleophilic attack fails. Drastic conditions ($300^\circ C$ and high pressure) are mandatory to force the substitution.
