Vedclass · Answer

(B) The reaction of cyclohexene with $Br_2$ in $CCl_4$ is an electrophilic addition reaction. This reaction proceeds via the formation of a cyclic bromonium ion intermediate. The bromide ion $(Br^-)$ attacks the cyclic bromonium ion from the side opposite to the bromonium bridge,resulting in anti-addition. For cyclohexene,this anti-addition of bromine atoms results in the formation of trans-$1,2$-dibromocyclohexane. Since the product is a pair of enantiomers (trans-$1,2$-dibromocyclohexane exists as $(1R, 2R)$ and $(1S, 2S)$ forms),the resulting mixture is a racemic mixture.
