Vedclass · Answer

(A) The acidity of carboxylic acids is increased by the presence of electron-withdrawing groups $(EWG)$ due to the $-I$ (inductive) effect.The strength of the $-I$ effect for halogens follows the order of their electronegativity:$F > Cl > Br$.Therefore,the electron-withdrawing power decreases in the order $F > Cl > Br$,which stabilizes the conjugate base (carboxylate ion) more effectively in the order $FCH_2COO^- > ClCH_2COO^- > BrCH_2COO^-$.Thus,the correct order of relative acidity is $FCH_2COOH > ClCH_2COOH > BrCH_2COOH$.

Which of the following is the correct order of relative acidity for the given acids?
