The compound formed by the reaction of ethanal with semicarbazide contains _______ number of nitrogen atoms.

Correct answer

Step-by-step solution

Semicarbazide is the chemical compound with the formula OC ( NH 2 ) ( N 2 H 3 ) . It is a water-soluble white solid. It is a derivative of urea. Acetaldehyde reacts with semicarbazide give acetaldehyde semicarbazone, the reaction will be Hence the product formed has three nitrogen atoms in it.
