Vedclass · Answer

(C) The acid strength of carboxylic acids is directly proportional to the $-I$ (inductive) effect of the substituents attached to the alpha-carbon.As the number of electron-withdrawing groups increases,the $-I$ effect increases,which stabilizes the conjugate base (carboxylate ion) and increases the acidity.In $Cl_3C-COOH$,there are three chlorine atoms exerting a strong $-I$ effect,whereas the other options have only one halogen atom.Therefore,$Cl_3C-COOH$ is the strongest acid.

Which among the following carboxylic acids is the strongest acid?
