Which of the following conversions is Hofmann Elimination reaction?

Options

  1. ARCONH ₂ Br ₂, KOH _ ( aq ) R - NH ₂
  2. BR - NH ₂ [ excess ] R - X R ₄ NX
  3. CR ₄ NX [ ] moist Ag ₂ O Alkene + R ₃ ~N
  4. DRCN Na / C₂ H ₅ OH RCH ₂ NH ₂

Correct answer

C. R ₄ NX [ ] moist Ag ₂ O Alkene + R ₃ ~N

Step-by-step solution

The Hofmann elimination reaction is a reaction in which a primary amide (RCONH2) undergoes elimination to form an amine and an alkene. This is typically done using excess aqueous potassium hydroxide ( KOH ) .
