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...
