Ketone with nh2oh
WebWhen semicarbazide reacts with a ketone (or aldehyde) to form semicarbazone. Only one nitrogen atom of semicarbazide acts as a nucleophile and attack the carbonyl carbon of the ketone. The product of the reaction consequently is R2–C=N–NH–CONH2 rather than R2–C=NCONH–NH2. Web31 mrt. 2024 · Nucleophiles, like ammonia and its derivatives H2N-Z gets added to the carbonyl group of aldehydes and ketones. The reaction is reversible and catalyzed by acid. These reactions are called condensation reactions because there is a loss of a molecule of water to give the product.
