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 include wedges and dashes for the Fischer Projections. Make sure to include the configuration for the first Fischer Projection.

For CH3CH2CH(CH2OH)CH2OH: 1. Carefully draw a structures of the molecule and its mirror image using proper stereochemical notation. The mirror images should be drawn side-by-side indicating the mirror plane. Structures should be drawn USING THE ZIG-ZAG STYLE WITH WEDGES AND DASHES. 2. Determine if the mirror images can be superposed and therefore if they are enantiomers and/or diastereomers. 3. Identify the stereogenic center(s) of the molecule. 4. Determine the configuration at each stereogenic center (R or S). 5. For compounds...
