Vedclass · Answer

(A) The acidic strength of aromatic carboxylic acids is influenced by the electronic effect of the substituent group attached to the benzene ring.Electron-withdrawing groups $(EWG)$ like $-Cl$,$-CN$,and $-NO_{2}$ stabilize the carboxylate anion through inductive and/or resonance effects,thereby increasing the acidic strength.Conversely,electron-donating groups $(EDG)$ like $-NH_{2}$ destabilize the carboxylate anion by increasing electron density,which decreases the acidic strength of the aromatic carboxylic acid.Therefore,$-NH_{2}$ is the group that decreases the acidic strength.

Which among the following substituent groups decreases the acidic strength of aromatic carboxylic acid?
