Solution

The correct option is C A, C and D
The addition of a hydrogen halide to an alkene follows Markovnikov's rule but in the presence of a peroxide, anti-Markovnikov's addition will be followed. The peroxide effect does not hold good for $H C l$ and $H I$ . It is applicable only for $H B r$ as shown below:

$C H_{3} - C H = C H_{2} + H B r ⟶ C H_{3} - C | B r H - C H_{3}$
