Acetamide is treated with the following reagents separately. Which one of these would yield methyl amine?

  1. NaOH/Br2
  2. Sodalime
  3. Hot conc. H2SO4
  4. PCl5

Answer

(1) NaOH/Br2

Solution

Hoffmann bromamide degradation: an amide with Br2 and NaOH gives a primary amine with one carbon atom less.

CH3CONH2 + Br2 + 4NaOH CH3NH2 + Na2CO3 + 2NaBr + 2H2O

Answer: (1)
