Which of the following statements best explains the decreased acidic nature of carbonic acid compared to other carboxylic acids? OH carboxylic acid HO OH carbonic acid A. The extra hydroxyl group on the carbonic acid is an electron donating group, dampening the acidity of the molecule. B. The carbonyl group is an electron withdrawing group, increasing acidity of the OH through resonance. C. The carboxylate anion is stabilized by hyperconjugation and is a weak base, so the conjugate acid is...
