The reaction of propene with HBr in presence of peroxide proceeds through the intermediate

A

`H_(3)C-CH-CH_(3)`

B

`H_(3)C-CH-CH_(2)Br`

C

`H_(3)C-overset(Br)overset(|)CH-CH_(2)`

D

`H_(3)C-CH_(2)-CH_(2)`

Text Solution

Verified by Experts

The correct Answer is:
B

The intermediate produce in case of addition of HBr occurs according to antimarkonicov.s mle. Thus we get
`CH_(3)-CH-CH_(2)` Br as intermidiate
