Electron donating groups stabilize the arenium ion during S_EAr reactions.

Question

Quizplus · Accepted Answer

Electron donating groups (EDGs) are groups that have a positive inductive effect or a negative resonance effect, and they stabilize the positive charge on the benzene ring during S_EAr reactions. This is because they donate electrons to the benzene ring, which reduces the positive charge density and stabilizes the arenium ion intermediate. Examples of EDGs include -OH, -NH2, -NR2, -OR, -OAr, -SR, and -SAr groups.
