Solution

When propene reacts with HCl in presence of peroxide, the product is 2-chloro propane.

Explanation:

Because some of the steps in a chain reaction are endothermic, the reaction proceeds via Markovnikov's rule when propene combines with HCl in the presence of peroxide. 2-chloro propane is the end product.

The reaction is as follows:

\[\begin{array}{cc}
\ce{H2C = \underset{Propene}{CH - CH3} + HCl ->[Peroxide] CH3 - CH - CH3}\\
\phantom{...............................}|\\
\phantom{................................}\ce{\underset{2-chloro propane}{Cl}}
\end{array}\]
