Question Three a. For each chiral centre in the following molecules, assign an Ror S configuration. For full marks, you must clearly indicate the order of priority of the groups attached to each chiral centre, OH OH CH3 CH(OCH3)2 CHO b. Draw all stereoisomers of 2,3-dibromobutane (use 3D dash/wedge structures or Fischer projections to depict stereochemistry). Clearly identify enantiomers, diastereomers and meso compounds. Be sure to identify the stereocentres as Rors
