The intermediate formed during the addition of

\mathrm{HCl}

to propene in the presence of peroxide is

Options

A $\mathrm{CH}_{3} \mathrm{CHCH}_{2} \mathrm{CI}$
B $\mathrm{CH}_{2} \mathrm{CHCH}_{3}$
C $\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2}$
D $\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{C} \mathrm{H}_{2}$

Correct answer

B. $\mathrm{CH}_{2} \mathrm{CHCH}_{3}$

Step-by-step solution

The addition of HCl to propene proceeds by ionic mechanism and not by free radical mechanism. Hence it forms intermediate carbonium ion.
