Question
The reaction of a primary amine with chloroform and ethanolic KOH is called ______.
Options
Carbylamine reaction
Kolbe's reaction
Reimer-Tiemann reaction
Wurtz-Fittig reaction
Solution
The reaction of a primary amine with chloroform and ethanolic KOH is called Carbylamine reaction.
Explanation:
Carbylamine reaction involves the reaction of a primary amine with chloroform in presence of alcoholic KOH, that leads to the formation of isocyanide, and hence also known as Hofmann isocyanide synthesis.
For example: \[\ce{R - NH2 + CHCl3 + \underset{Alc.}{KOH} -> CHNC + 3KCl + 3H2O}\]
