Question

Hydrazones can often be used in the chemistry lab as a chemical test to identify aldehydes or ketones. In a mechanism analogous to imine formation, hydrazine can react with an aldehyde or ketone to form a hydrazone. Using 2,4-Dinitrophenylhydrazine or Brady's reagent, the presence of an aldehyde or ketone is indicated by a bright red precipitate. Identify hydrazine and a hydrazone in the list below.
