NEET levelSingle correct optionDifficulty 1 of 3o2062

Propene reacts with HBr in the presence of an organic peroxide. The major product is

  1. A (1-bromopropane)
  2. B (3-bromopropene)
  3. C (2-bromopropane)
  4. D (1,2-dibromopropane)

Answer: A

With peroxide, HBr adds by a free radical chain mechanism. adds to the terminal carbon to give the more stable secondary radical, which then abstracts H from HBr. The product is 1-bromopropane (anti-Markovnikov).
