  • A

    Figure
  • B
    $\mathrm{RCO} \mathrm{NH} \mathrm{CH}_{3}$
  • Correct answer
    C
    $\mathrm{RCONH}_{2}$
  • D
    $R C O O R$

Solution

In Hofmann bromamide reaction, primary amide reacts with bromine and sodium hydroxide to form isocyanate, which is hydrolysed to give primary amine (with one carbon less) aloner with decarboxylation.
