Question
Primary amine rects with carbon disulphide and HgCl2 to produce alkyl izsothiocyanate. This reaction is :
Options
A.Carbylamine reaction
B.Hoffmann mustand oil reaction
C.Perkin reaction
D.Hoffmann bromoamide reaction
Solution
The reaction is known as Hoffman mustard oil reaction.
R - NH2 + S = C = S → R - NH
SH 
R - N = C = S + HgS + 2HCl
Alkyl isothiocyanate
R - NH2 + S = C = S → R - NH
SH R - N = C = S + HgS + 2HClAlkyl isothiocyanate
