$CH_3-CH=CH_2 \underset{\text{Peroxide}}{\xrightarrow{HBr}} CH_3-CH_2-CH_2Br$

(B) The reaction of propene with $HBr$ in the presence of peroxide (Kharasch effect) proceeds via a free radical mechanism.In this mechanism,the bromine radical $(\dot{Br})$ attacks the double bond to form a more stable secondary free radical intermediate $(CH_3-\dot{C}H-CH_2Br)$.This secondary free radical then abstracts a hydrogen atom from $HBr$ to form the final product,$1$-bromopropane $(CH_3-CH_2-CH_2Br)$.
