Answer:

  • 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 will then regenerate the original carbonyl compounds.

Answer:

2,4-Dinitrophenylhydrazine can be used to qualitatively detect the carbonyl functionality of a ketone or aldehyde functional group. A positive test is signalled by the formation of a yellow, orange or red precipitate (known as a dinitrophenylhydrazone).
