Question

Quizplus · Accepted Answer

The strength of a carboxylic acid is influenced by the electron-withdrawing ability of substituents attached to the carbon atom adjacent to the carboxyl group. Fluorine (F) is the most electronegative element among the options given, thus it exerts the strongest electron-withdrawing effect through induction. This stabilizes the carboxylate anion more effectively, making the corresponding acid (D) FCH2COOH the strongest acid among the options listed.
