Stereochemistry of bromine addition 1) To investigate the mechanism for the addition of bromine to an alkene, we will use the melting point of our brominated products. The three possible outcomes for this lab are to obtain 1)only the syn enantiomers, 2)only the anti enantiomers, or 3)a mixture of diastereomers. Match these possible outcomes to the three possible mechanisms described in the lab manual, bromonium ion, concerted Br2 activation, and carbonation 2) In this experiment we don't crystallize the final...
