In electrophilic aromatic substitution reactions, a -CO₂H substituent on the aromatic ring is ________.

Question

Quizplus · Accepted Answer

The -CO₂H substituent is a meta-deactivator because it withdraws electron density from the ring through the sulfur atom, which is a moderately good electron-withdrawing group. This decreases the nucleophilicity of the ring, making it less reactive towards electrophiles. The -CO₂H group is not a director because it does not facilitate the attack of electrophiles at a specific position on the ring.
