what happens when ethylamine is heated with hgcl2 in the presence of cs2.
Answers
H2 gas is evolved. 14) Hofmann Mustard Oil reaction : Ethylamine reacts with Carbon di sulphide (CS2) & Mercuric chloride (HgCl2) to form ethyl isothiocyanate which has smell like mustard oil.
its the answer....
Answer:
Ethylamine when heated with HgCl₂ in the presence of CS₂ forms ethyl isocyanate, with the odour of mustard oil.
Explanation:
The Hofmann-Mustard Oil Reaction is an organic reaction that produces isothiocyanates by heating primary amines with carbon disulfide (CS₂) and excess mercury chloride ( HgCl₂). These isothiocyanates produce an unpleasant odour which is similar to that of mustard oil.
The Hoffman mustard oil reaction is used to distinguish between primary, secondary and tertiary amines.
Ethylamine on heating with HgCl₂ in the presence of CS₂ gives ethyl isocyanate as the end product of the reaction.
The reaction is shown below.
C₂H₅NH₂ + CS₂ + HgCl₂ → C₂H₅NCS + 2HCl + HgS
