Vedclass · Answer

(D) The acidic strength of carboxylic acids depends on the electron-withdrawing effect of substituents. Electron-withdrawing groups $(EWG)$ increase acidity by stabilizing the carboxylate anion,while electron-donating groups decrease it.$A$. $CH_2FCH_2CH_2COOH $B$. $CH_2ClCOOH $C$. $CH_3COOH $D$. $HCOOH < C_6H_5COOH$: Incorrect. Formic acid $(HCOOH)$ is more acidic than benzoic acid $(C_6H_5COOH)$ because the phenyl group in benzoic acid is electron-donating by resonance and has a weaker $-I$ effect compared to the hydrogen atom in formic acid. Thus,the correct order is $C_6H_5COOH < HCOOH$.
