How can you predict the stereochemistry of bromine?
You are to determine, based on the melting point of your product, which pair of enantiomers is produced. By knowing which enantiomeric pair is formed one can predict a plausible mechanism. Hint: you can predict the stereochemical outcome of a syn vs. anti addition of bromine to alkenes before you step foot into the laboratory.
