Which of the following statement about the effects of substituents groups on acidity of carboxylic acid is INCORRECT? a. The higher acidity of carboxylic acid is due to stabilization of carboxylate ion by two equivalent resonance structures in which negative charge is at more electronegative oxygen atom. b. Electron withdrawing groups increase the acidity of carboxylic acid by weakening O–H bond. c. Electron donating groups decrease the acidity of carboxylic acid by increasing strength of O–H bond. d. Electron withdrawing groups can stabilize conjugate base through the delocalization of the radical charge on the hydrogen atom.
