Identify the major product of following reaction. Propene [ Peroxide ] HBr ,?

Options

  1. A1 - Bromopropane
  2. B2 - Bromopropane
  3. C3 - Bromopropene
  4. D2 - Bromopropan-1-ol

Correct answer

A. 1 - Bromopropane

Step-by-step solution

The reaction of propene with HBr in the presence of peroxide proceeds via a free radical mechanism, known as the peroxide effect or anti-Markovnikov addition. The peroxide undergoes homolytic cleavage to form alkoxy radicals, which then abstract a hydrogen atom from HBr to generate a bromine radical ( Br^ ). The bromine radical adds to the less substituted carbon atom of the double bond in propene to generate a more stable secondary free radical: CH₃-CH=CH₂ + Br^ CH₃- C H-CH₂Br The secondary free radical then abstr
