Question

what
happen when ethylamine is
heated with Hgcl2
in the presence of
Cs2?​

Answer 1

H2 gas is released.......

Answer 2

Given: Ethylamine is heated with $HgCl_{2}$ in presence of a solvent carbon disulphide $CS_{2}$.

To find: Products formed on heating of ethylamine with mercurous chloride in presence of carbon disulphide

Explanation: Ethylamine is a aliphatic amine known by the chemical formual $C_{2} H_{5} NH_{2}$ is heated with mercurous chloride in the presence of carbon disulphide. It is the name reaction hoffman mustard oil reaction which is given by only primary amines.In this reaction there is a black precipitate which is formed at the end of the reaction which indicates the amine as primary amine. And this black precipitate is due to mercuric sulphate HgS. It leads to formation of isothiocyanates.

The reaction is given as follows

$C2_{} H_{5}NH_{2}$$+CS2_{}+HgCl_{2} =C_{2} H_{5}NCS$
