Vedclass · Answer

(A) The reaction of cyclohexene with $Br_2$ in the presence of water $(H_2O)$ is a halohydrin formation reaction. In this reaction,the electrophilic bromine atom adds to the double bond to form a cyclic bromonium ion intermediate. Water,acting as a nucleophile,then attacks the more substituted carbon atom of the bromonium ion from the side opposite to the bromine atom (anti-addition). This results in the formation of $2$-bromocyclohexanol,where the $-Br$ and $-OH$ groups are in a trans configuration. The product is a racemic mixture of the two enantiomers of $trans-2$-bromocyclohexanol.
