Vedclass · Answer

(D) The acidic strength of carboxylic acids is directly proportional to the electron-withdrawing effect ($-I$ effect) of the substituents attached to the alpha-carbon.As the number of chlorine atoms increases,the $-I$ effect increases,which stabilizes the carboxylate anion by dispersing the negative charge.Therefore,the order of acidic strength is: $CH_3COOH Thus,$CCl_3COOH$ is the strongest acid.
