Vedclass · Answer

(B) The addition of $HCl$ to propene follows Markovnikov's rule,even in the presence of peroxide,because the peroxide effect (Kharasch effect) is only applicable to $HBr$.In the reaction,the electrophile $H^+$ attacks the double bond to form the more stable secondary carbocation,$CH_3-CH^{+}-CH_3$.Since the secondary carbocation is more stable than the primary carbocation $(CH_3-CH_2-CH_2^+)$,it acts as the reaction intermediate.

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