Vedclass · Answer

(B) $2, 4-Dinitrophenylhydrazine$ $(2, 4-DNP)$ is a reagent used to identify aldehydes and ketones through a nucleophilic addition-elimination reaction,forming coloured crystalline $2, 4-dinitrophenylhydrazones$.Among the given options:$A$ $(CH_3COCl)$ is an acyl chloride.$B$ $(CH_3COCH_3)$ is a ketone (acetone).$C$ $(CH_3CO(OC_2H_5))$ is an ester (ethyl acetate).$D$ $(CH_3CONH_2)$ is an amide (acetamide).Only aldehydes and ketones react with $2, 4-DNP$ to form the characteristic coloured crystalline derivatives. Therefore,acetone $(CH_3COCH_3)$ is the correct answer.

Which of the following compounds containing a carbonyl group will give a coloured crystalline compound with $2, 4-DNP$?
