Chemistry · Aldehydes and Ketones

OPTION A: Aldehydes react with ammonia to form a primary amine through Hartmann's nitration or Hofmann rearrangement.

OPTION B: The reaction of aldehydes and ketones with ammonia or 1°-amines forms imine derivatives, also known as Schiff bases (compounds having a C=N function). Water is eliminated in the reaction, which is acid-catalyzed and reversible in the same sense as acetal formation.

OPTION C: Aldehydes react with ammonia to form nitriles. Nitriles are a functional group in organic chemistry that contains a carbon atom triple-bonded to a nitrogen atom.

OPTION D: Aldehydes can react with hydrazine (NH₂-NH₂) to form Hydrazones, which are compounds containing a hydrazone group (-C=N-NH-).
