Question

Give a chemical test to distinguish between Aniline and Ethanamine. [Uttarakhand 2019]

Answer 1

Answer:

HELLO DEAR,

Ethylamine Is A Primary Aliphatic amine while aniline is a primary aromatic amine.

this may be distinguished by azo dye test :

it involves the reaction of any aromatic primary amine with HNO2(NaNO2 + dil. HCl) at 273 — 278 Kelvin followed by treatment with an alkaline solution of 2—naphthol (Beta naphthol) when a brilliant Orange or red colour dye is obtained.

[see the attachment]

aliphatic primary amine ethylamine under these conditions give a brisk evolution of N2 gas with the formation of primary alcohol i.e the solution remains clear

I HOPE IT'S HELP YOU DEAR,

THANKS
