Vedclass · Answer

(B) The reaction of bromine with ethene proceeds through the formation of a cyclic bromonium ion intermediate. In a solvent like methyl alcohol $(CH_3OH)$,the cyclic bromonium ion can be attacked by either the bromide ion $(Br^-)$ or the solvent molecule $(CH_3OH)$ acting as a nucleophile. Attack by $Br^-$ leads to the formation of $1, 2-dibromoethane$,while attack by $CH_3OH$ followed by deprotonation leads to the formation of $BrCH_2CH_2OCH_3$.

In methyl alcohol solution,bromine reacts with ethylene (ethene) to yield $BrCH_2CH_2OCH_3$ in addition to $1, 2-dibromoethane$ because
