The intermediate carbocation can react with either $Br^-$ or $CH_3OH$.

Vedclass · Answer

(A) The reaction of ethylene with $Br_2$ proceeds via the formation of a cyclic bromonium ion intermediate. In the presence of a nucleophilic solvent like methanol $(CH_3OH)$,the solvent can attack the electrophilic carbon of the bromonium ion. This leads to the formation of the bromo-methoxy product $(BrCH_2CH_2OCH_3)$ alongside the standard $1, 2-$dibromoethane formed by the attack of $Br^-$.

The reaction of ethylene with bromine in a methanol solution yields $1, 2-$dibromoethane as well as $BrCH_2CH_2OCH_3$. This is because ......
