Vedclass · Answer

(D) The acidity of carboxylic acids is increased by the presence of electron-withdrawing groups ($-I$ effect) attached to the alpha-carbon.Chlorine atoms exert a strong $-I$ effect,which stabilizes the carboxylate anion by dispersing the negative charge.As the number of chlorine atoms increases,the $-I$ effect increases,thereby increasing the acidity.The order of acidity is: $Cl_3CCOOH > Cl_2CHCOOH > ClCH_2COOH > CH_3COOH$.Therefore,$Cl_3CCOOH$ (trichloroacetic acid) is the strongest acid.
