  2. BHofmann bromamide reaction
  3. CStephens reaction
  4. DGabriels phthalimide synthesis

Correct answer

B. Hofmann bromamide reaction

Step-by-step solution

CH3−C||O−NH2+Br2+4NaOH→ΔCH3−NH2+2NaBr+Na2CO3+3H2O{\text{CH}}_{3} - \overset{\overset{\text{O}}{\text{||}}}{\text{C}} - {\text{NH}}_{2} + {\text{Br}}_{2} + 4 \text{NaOH} \overset{\Delta}{\to} {\text{CH}}_{3} - {\text{NH}}_{2} + 2 \text{NaBr} + {\text{Na}}_{2} {\text{CO}}_{3} + 3 {\text{H}}_{2} \text{O}

This is Hofmann bromamide reaction.
