Aldehydes and ketones undergo nucleophil...

Aldehydes and ketones undergo nucleophilic addition reactions. With weak nucleophiles such as ammonia and its derivatives, `(H_2 N-Z)`, aldehydes and ketones react in weakly acidic medium to form compounds containing carbonnitrogen double bond with the elimination of water to form . Aldehydes can be easily oxidised to carboxylic acid on treatment with common oxidising agents like `KMnO_4 K_2 Cr_2 O_7 , HNO_3`, etc. The carboxylic acid formed contain the same number of carbon atoms as the aldehydes. However ketones under drastic conditions with powerful oxidising agents undergo cleavage of C-C bond giving mixture of carboxylic acids having lesser number of C atoms than the original ketone.
