Draw all the stereoisomers (redraw the first with the proper 3-D
representation) of the compounds below. The configuration for the
first isomer you should draw is provided. Assign R or S
configuration to each chirality center in the additional isomers.
Indicate the stereochemical relationship (diastereomers,
enantiomers, meso compounds) between the first isomer and each of
the others. The configuration for the Fischer Projection has been
omitted, since stereochemistry can be determined from a 2-D
structure. You do not need to...

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
