Vedclass · Answer

(B) $3$-Phenylpropene $(C_6H_5CH_2CH=CH_2)$ reacts with $HBr$ via electrophilic addition.According to Markownikoff's rule,the electrophile $(H^+)$ adds to the terminal carbon to form a more stable secondary benzylic carbocation $(C_6H_5CH^+CH_2CH_3)$.The nucleophile $(Br^-)$ then attacks this carbocation to form the major product,$1$-bromo-$1$-phenylpropane $(C_6H_5CH(Br)CH_2CH_3)$.
