The acidity of a molecule is determined by the stability of its conjugate base. In this case, the conjugate base is the carboxylate anion (RCOO-). The more stable the conjugate base, the more acidic the original molecule. The stability of the carboxylate anion is increased by electron-withdrawing groups, which help to disperse the negative charge. In this case, the halogens (Cl, Br, I, F) are the electron-withdrawing groups. The strength of the electron-withdrawing effect decreases down the group (F Cl Br I). Therefore, the acidity of the molecules decreases in the same order: FCH2COOH ClCH2COOH BrCH2COOH ICH2COOH. So, the increasing order of acidity is: ICH2COOH

Question

The acidity of a molecule is determined by the stability of its conjugate base. In this case, the conjugate base is the carboxylate anion (RCOO-). The more stable the conjugate base, the more acidic the original molecule. The stability of the carboxylate anion is increased by electron-withdrawing groups, which help to disperse the negative charge. In this case, the halogens (Cl, Br, I, F) are the electron-withdrawing groups. The strength of the electron-withdrawing effect decreases down the group (F > Cl > Br > I). Therefore, the acidity of the molecules decreases in the same order: FCH2COOH > ClCH2COOH > BrCH2COOH > ICH2COOH. So, the increasing order of acidity is: ICH2COOH < BrCH2COOH < ClCH2COOH < FCH2COOH.
