Question

what is hinsberg reagent test for distinguishing between primary, secondary and teritary amines?

Answer 1

butter is kept in wet cloth during summers because, when butter is kept in room temperature it melts.therefore in order to protect it from melting,It is wrapped in a wet cloth.the wet cloth contains water,which evaporates by taking latent heat of fusion from the butter and thus helps in keeping the butter cool and protects it from melting.

Answer 2

The Hinsberg reaction is a chemical test for the detection of amines i.e distinguishing between primary, secondary and teritary amines . In this test when we add Hinsberg reagent in the presence of aqueous alkali NaOH to given amine , if it forms soluble sulfonamide then it is primary amine , if insoluble sulfonamide then secondary amine and for for tertiary amine it will not give reaction when we will add aqueous sodium hydroxide solution and benzenesulfonyl chloride is added to a substrate in the reaction .

Hope it will help u ....
