give chemical test to distinguish between 1)aniline and ethylamine 2) Methyamine nad dimethylamine.
Part : I
1) Aniline and Ethylamine
Aniline gives positive test for coupling reaction.
Aniline reacts with benzene diazonium chloride in basic medium to give p-aminoazobenzene which is yellow in colour
Ethylamine does not give coupling reaction.
Reaction Involved :
Part - II
Methylamine and dimethylamine :
Methylamine is a primary amine hence it give carbylamine test. Dimethylamine being a secondary amine will not give
carbylamine test.
Reaction invovled :
