What is the rate determining step in an S_NAr reaction?

Question

Quizplus · Accepted Answer

In an S_NAr reaction, the rate determining step would involve the nucleophilic attack of the aromatic ring. This is because the reaction involves the substitution of a leaving group on an aromatic ring, which is typically a slow step due to the high stability of the aromatic system. The nucleophilic attack by the incoming species is what allows for the displacement of the leaving group, but the rate of this step can be hindered by the aromatic system's stability. Therefore, the rate determining step is typically the nucleophilic attack.
