The reaction of a primary amine with chloroform and ethanolic KOH is called ______.
पर्याय
Carbylamine reaction
Kolbe's reaction
Reimer-Tiemann reaction
Wurtz-Fittig reaction
उत्तर
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: \[\ce{R - NH2 + CHCl3 + \underset{Alc.}{KOH} -> CHNC + 3KCl + 3H2O}\]

A primary amine, \[\ce{RNH2}\] can be reacted with \[\ce{CH3-X}\] to get secondary amine, \[\ce{R-NHCH3}\] but the only disadvantage is that 3° amine and quaternary ammonium salts are also obtained as side products. Can you suggest a method where \[\ce{RNH2}\] forms only 2° amine?
Assertion: Acetanilide is less basic than aniline.
Reason: Acetylation of aniline results in decrease of electron density on nitrogen.
