Vedclass · Answer

(D) The acidity of carboxylic acids is increased by the presence of electron-withdrawing groups (EWGs) attached to the alpha-carbon. $F$ is more electronegative than $Cl$,so fluorine-substituted acetic acids are stronger than chlorine-substituted ones. Among the given options,$CHF_2COOH$ contains two highly electronegative $F$ atoms,which exert a strong inductive effect ($-I$ effect) to stabilize the carboxylate anion. Therefore,$CHF_2COOH$ is the strongest acid.
