Many nucleophilic addition reactions of aldehydes and ketones are catalyzed by acid or base. Bases catalyze hydration by: a. making the carbonyl group more electrophilic b. shifting the equilibrium of the reaction c. making the carbonyl group less electrophilic d. converting the water to hydroxide ion, a much better nucleophile
