Answer: (B) acetylation of morphine. Answer: (B) acetylation of morphine Solution: Heroin (smack), chemically diacetylmorphine, is produced by the acetylation of morphine, which itself is extracted from the latex of the opium poppy Papaver somniferum.

  1. A.methylation of morphine
  2. B.acetylation of morphine✓
  3. C.glycosylation of morphine
  4. D.nitration of morphine

Correct Answer

(B) acetylation of morphine

Solution & Explanation

Answer: (B) acetylation of morphine Solution: Heroin (smack), chemically diacetylmorphine, is produced by the acetylation of morphine, which itself is extracted from the latex of the opium poppy Papaver somniferum. It is an opioid depressant that slows down body functions. Why others are wrong: Methylation, glycosylation and nitration are not the reactions used; NCERT specifically names acetylation. NCERT Reference: NCERT Ch7, p.142, lines 32-36: "This is obtained by acetylation of morphine"
