The statements given below contains assertion and reason. Choose the correct option
Assertion (A): Propene reacts with HBr in presence of organic peroxide gives 1-bromopropane.
Reason(R): The reaction occurs through carbocation intermediate
- A A is false but R is true
- B A is true but R is false
- C Both A and R are true but R is not the correct explanation of A
- D Both A and R are true, R is the correct explanation of A
Answer & Solution
Correct Answer
(B) A is true but R is false
Step-by-step Solution
Detailed explanation
Propene reacts with HBr in the presence of an organic peroxide to give 1-bromopropane. This is known as the peroxide effect or Kharasch effect, which follows anti-Markovnikov addition. Thus, the assertion is true. The reaction proceeds via a free radical mechanism involving a…
