Aldehydes and ketones are amphoteric. Thus they can act both as acids and bases. Under acidic conditions, the carbon of the protonated canbonyl group is much more electrophilic, reacting even with weak nucleopphilie. Carbonyl compound gives nucleophilic addition reaction. In this reaction the nucleophilic attack proceeds the elecrophilic attack.

B. oxygen nucleophile
C. Nitrogen nucleophile
D. All of these
