WebAldehydes and ketones react to yellow, orange, or reddish-orange precipitates with the 2,4-dinitrophenylhydrazine reagent, whereas alcohols do not react. This is a successful technique for checking for the existence of a drug or demonstrating its absence. Why does glucose not give a 2,4 DNP test? WebAldehydes and ketones are simple compounds which contain a carbonyl group - a carbon-oxygen double bond. They are simple in the sense that they don't have other reactive groups like -OH or -Cl attached directly to the carbon atom in the carbonyl group - as you might find, for example, in carboxylic acids containing -COOH.
