JEE Main levelOne or more correct optionsDifficulty 2 of 3o2088

Which of the following statements about the peroxide effect are correct?

  1. AIt operates for HBr but not for HCl or HI
  2. B adds first to give the more stable carbon radical
  3. CThe mechanism involves a carbocation that may rearrange
  4. DPropene gives 1-bromopropane as the major product under these conditions

Answer: A, B, D

The peroxide effect is a radical chain reaction specific to HBr. adds to the terminal carbon of propene to give the secondary radical, so 1-bromopropane forms. No carbocation occurs, so statement C is false.
