The Hinsberg Test -

This test can be used to demonstrate whether an amine is primary, secondary or tertiary.Primary amines react with benzene sulfonyl chloride to form N - substituted benzene sulfonamides.These, in turn, undergo acid-base reactions with the excess potassium hydroxide to form water soluble potasssium salt. Acidification of this solution will cause the water soluble in the next stage, cause the water- insoluble  N - substituted sulfonamide to precipitate.

C_{6}H_{5}SO_{2}Cl is Hinsberg's reagent,

Hinsberg's reagent is used for the detection of primary, secondary and tertiary amine 

C_{6}H_{5}SO_{2}Cl+\:-NH_{2}(P.A.)\rightarrow soluble\:\:in\:\:alkali

C_{6}H_{5}SO_{2}Cl+\:-NH-(S.A.)\rightarrow insoluble\:\:in\:\:alkali

C_{6}H_{5}SO_{2}Cl+     (T.A.)\rightarrow No\:\:reaction

 


Option 1)

C_{6}H_{5}COCl

Option 2)
