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...
