Question

(a) Give one chemical test to distinguish between aniline and N-methyl aniline.

(b) Dimethyl amine is a stronger base than methyl amine (Give reason).

(c) How will you obtain from aniline (Give equations only) –

(i) 2, 4, 6-tribromoaniline?

(ii) Benzene diazonium chloride?

Answer 1

(a) Isocynide test (carbile amine reaction)

(b) Because in Di-methyl amine have two e^– donar (+I) CH₃ – group which are increases the e^– density on N – atom as well as increases the basicity of amine.
