Question

Quizplus · Accepted Answer

Electron withdrawing groups (EWGs) decrease the electron density in the aromatic ring, thereby making it more susceptible to electrophilic substitution reactions like S_NAr reactions. The EWGs stabilize the positively charged intermediate formed during the reaction, thus promoting the reaction.
