  3. CHoffmann-bromamide reaction
  4. DCarbylamine reaction

Correct answer

D. Carbylamine reaction

Step-by-step solution

The reaction, R N H 2 + C H C l 3 + 3 K O H E t h a n o l i c → R - N + ≡ C - + 3 K C l + 3 H 2 O is called Carbylamine reaction Mechanism CHCl 3 + KOH → CCl 2 (Electrophilic carbene) +   H 2 O   +   KCl R - N . . H 2 + : C C l 2 → R - + N | | H H - C | | : - C l C l → 2 K O H - 2 H C l R - N + ≡ C -
