The nucleophilic substitution reactions taking place in aromatic syste

1.	The nucleophilic substitution reactions taking place in aromatic system are designated as SN ArIn fact aryl halides do not easily undergo nucleophilic substitution under ordinary conditions. However, introduction of electron- withdrawing groups in o, p – positions makes the reaction to go faster. Keeping these general points in view answer the following questionsWhich of the following undergo nucleophilic substitution at a faster rate with a given nucleophilic
Answer» SOLUTION :As it CONTAINS two EWG - `S_(N) Ar` is faster than others
