5) Bromine reacts with cyclohexene to form 1,2-dibromocyclohexane. a) Draw all the unique stereoisomers of 1,2-dibromocyclohexane and identify any enantiomeric pairs. Are any of these compounds meso compounds? [3] b) Identify one of the isomers you drew for (a) and: i) demonstrating the use of the CIP rules, assign R/S to any stereogenic centres in this compound; ii) draw the lowest energy conformation of this molecule. 141 c) Give a mechanism for this reaction between bromine and cyclohexene, and therefore justify which isomer(s) you drew in (a) is/are formed, and in what ratio if multiple isomers are formed.
