Question

Distinguish between the chemical test between .Acetone and butan2one
​

Answer 1

Answer:

Carbonyl compounds such as aldehydes and ketones reacts readily with derivatives of ammonia containing a hetero atom attached to the ammonia nitrogen to give stable solid derivatives with sharp melting points. A well known examples of those derivatives of ammonia containing a hetero atom attached to the ammonia are hodroxyl amine (H2N−OH), semicarbazide (H2N−NH−C(=O)−NH2), and phenylhydrazine (Ph−NH−NH2). The most common phenylhydrazine used is 2,4-dinitrophenylhydrazine (2,4-DNP), because it gives hydrazone derivative, which can be used as qualitative test for these carbonyl compounds.
