Vedclass · Answer

(C) $2,4$-Dinitrophenylhydrazine $(D.N.P.)$ test is a characteristic reaction used for the identification of carbonyl compounds (aldehydes and ketones).$D.N.P.$ reacts with the carbonyl group $(>C=O)$ to form a yellow,orange,or red precipitate.$CH_3-CHO$ (acetaldehyde) is an aldehyde,so it gives the test.$CH_3-CO-CH_3$ (acetone) is a ketone,so it gives the test.$C_6H_5-CHO$ (benzaldehyde) is an aldehyde,so it gives the test.$CH_3-O-CH_3$ (dimethyl ether) is an ether,not a carbonyl compound,so it will not give the $D.N.P.$ test.
