Hey folk..
Hinsberg reactions is the answer--------
In this Hinsberg test, an amine is reacted with benzene sulfonyl chloride. But the product forms is amine , either a primary or secondary amine, because tertiary amines do not form stable sulfonamides----
----(but we cannt say that tertiary amines not at all form, actually bcoz of it's unstabilty it has a neglegible fraction so we neglect it)----
If the sulfonamide that forms dissolves in aqueous sodium hydroxide solution, it is a primary amine. If the sulfonamide is insoluble in aqueous sodium hydroxide, it is a secondary amine. The sulfonamide of a primary amine is soluble in an aqueous base because it still possesses an acidic hydrogen on the nitrogen, which can be lost to form a sodium salt.
