Which of the following compound gives dye test ?a)Anilineb)Methylamine...
Aniline gives the dye test.
Explanation:
The dye test is used to distinguish primary amines from secondary amines. The test involves the reaction of the amine compound with sodium nitrite (NaNO2) and hydrochloric acid (HCl) to form a diazonium salt, which is then reacted with a coupling agent to form a colored product.
In the case of primary amines, the diazonium salt is stable and can be coupled with phenol or its derivatives to form a colored azo dye. On the other hand, secondary amines do not give a positive result in the dye test because they do not form stable diazonium salts.
Aniline is a primary amine, and it readily forms a diazonium salt when treated with NaNO2 and HCl. This diazonium salt can be coupled with phenol or its derivatives to form a colored azo dye, which confirms the presence of a primary amine. Hence, aniline gives the dye test.
