2,4-DNP derivatives offer a convenient way of separating the components of a mixture of aldehydes and ketones. Rather than attempting to do this directly by fractional distillation, a chemist might take advantage first of the easy separation of 2,4-DNP derivatives by column chromatography. Since their formation from aldehydes and ketones is reversible, hydrolysis of the separated derivatives.

2,4 DNP test is for aldehydes (R-C(O)-H) and ketones (R1-C(O)-R2). When 2,4-DNP reacts with either, it leads to the formation of a precipitate. Chromic acid test is for aldehydes and alcohols. When either reacts with chromic acid, bright orange color of Cr2O7(2-) changes to dark green of Cr(3+) and organic compound is being oxidized to. (ii) It forms a 2, 4-DNP derivative and reduces Tollen's reagent. It must be an aldehyde. (iii) Since it undergoes Cannizzaro's reaction, therefore CHO group is directly attached to the benzene ring. (iv) On oxidation it gives 1,2-benzenedicarboxylic acid, therefore it must be an ortho-substituted benzaldehyde, so the structure should be. Question 73. (a) Give chemical tests to distinguish. Oxidation of a 2-butanol into the ketone 2-butanone, a 2,4-DNP derivative and then crystallizing the product. It was quite the vibrant orange. 1 comment. share. save. hide. report. 100% Upvoted.
