Which of the following hydrogen halides in the presence of peroxides undergoes addition reaction with propene in an anti-Markovnikov fashion?

A

`HBr`

B

`HF`

C

`HCl`

D

`Hl`

Text Solution

Verified by Experts

The correct Answer is:
A
Anti-Markovnikov's addition (peroxide effect) occurs only when `HBr` is used in the presence of peroxides and does not occur significantly with `HF, HCl`, and `Hl` even when peroxides are present. This is due to the fact that is `HBr` case both the propagation steps are exhothermic.
