Give one chemical test to distinguish between the following pairs of compounds.
Methylamine and diethylamine.
Give one chemical test to distinguish between the following pairs of compounds.
Secondary and tertiary amines.
Shake the given amines separately with Hinsberg’s reagent (benzene sulphonyl chloride) in the presence of an excess of aqueous KOH solution.
A secondary amine forms N,N—dialkyl benzene sulphonamide which remains insoluble in aqueous KOH and even after acidification with dilute HCl.
A tertiary amine does not react with benzene sulphonyl chloride and remains insoluble in aqueous KOH.
