2. The product of this reaction contains two stereocenters. Due to the stereospecificity of the bromination and the symmetry of the product, however, only the meso-diastereomer of stilbene dibromide is produced.
a) How many possible stereoisomers exist for stilbene dibromide?
b) You formed one of the possible stereoisomers as the product of the bromination reaction (see the Reaction Scheme and Question 1). Draw all of the other possible stereoisomers, and label each stereocenter (R or S).
c) How are the stereoisomers that you drew in part (b) related to each other?
d) How are the stereoisomers that you drew in part (b) related to the product of the reaction shown in the Reaction Scheme?
