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

Options

  1. AP C l 5
  2. BN a O H/ B r 2
  3. CSodalime
  4. DHot conc. H 2 S O 4

Correct answer

B. N a O H/ B r 2

Step-by-step solution

Acetamide on reaction with B r 2 / K O H gives methylamine it is known as Hoffmann Bromamide reaction. C H 3 C O N H 2 + B r 2 + 4 K O H → C H 3 N H 2 + K 2 C O 3 + 2 K B r + 2 H 2 O
