The intermediate during the addition of `HCl` to propene in the presence of peroxide is :

Options

A. `CH_(3)overset(.)(C )HCH_(2)Cl`
B. `CH_(2)overset(+)(C )HCH_(3)`
C. `CH_(3)CH_(2)overset(.)(C )H_(2)`
D. `CH_(3)CH_(2)overset(.)(C )H_(2)`

Answer

B

Explanation

There is no effect of peroxide on the addition of HCl to an alkene. As the addition is electrophilic, the intermediate formed is a `2^(@)` carbocation (which is more stable than the `1^(@)` carbocation).
`underset("Propene")(CH_(3)-CH)=CH_(2)overset(+H^(+))rarr underset(2^(@)-"carbocation")(CH_(3)-overset(+)(C )H_(2)-CH_(3))`
