Vedclass · Answer

(D) The reaction involves two steps with excess $HBr$ and heat:$1$. Cleavage of the ether linkage: The methoxy group $(-OCH_3)$ is protonated by $HBr$ to form an oxonium ion,which then undergoes $S_N2$ attack by $Br^-$ to yield $CH_3Br$ and a phenol derivative,$3$-vinylphenol.$2$. Electrophilic addition to the alkene: The vinyl group $(-CH=CH_2)$ undergoes electrophilic addition with $HBr$. According to Markovnikov's rule,the proton adds to the terminal carbon to form a stable benzylic carbocation $(Ar-CH^+-CH_3)$. The bromide ion then attacks this carbocation to form the final product,$3-(1-bromoethyl)phenol$.
