Vedclass · Answer

(A) The acidity of these compounds depends on the stability of their conjugate bases. $1$. $ClCH_2COOH$ is the strongest acid due to the strong electron-withdrawing effect of the chlorine atom,which stabilizes the carboxylate anion. $2$. $HCOOH$ is stronger than $CH_3COOH$ because the methyl group in $CH_3COOH$ is electron-donating,which destabilizes the carboxylate anion. $3$. Phenol $(C_6H_5OH)$ is a much weaker acid than carboxylic acids because the negative charge on the phenoxide ion is less effectively delocalized compared to the resonance-stabilized carboxylate ion. Therefore,phenol is the weakest acid among the given options.
