Indicate which nitrogen compound amongst the following would undergo Hoffmann reaction (i.e., reaction with Br2 and strong KOH) to furnish the primary amine (R–NH2):

  1. RCONHCH3
  2. RCOONH4
  3. RCONH2
  4. R–CO–NHOH

Correct answer: RCONH2

Solution

The Hoffmann reaction specifically involves primary amides (RCONH2) reacting with Br2 and strong KOH to yield primary amines (R–NH2). Among the given options, only RCONH2 is a primary amide.
