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 that have more than one stereogenic center, carefully draw the stereoisomers using proper stereochemical notation. The mirror images should be drawn side-by-side indicating the mirror plane. Models should be drawn using the zig-zag style.
6. If there are more than 2 stereoisomers, perform a full stereochemical analysis of your structures, indicating which pairs are enantiomers and/or diastereomers. Identify the stereogenic center(s) of the molecule and determine the configuration at each stereogenic center.

3. Diastereomers and Meso Forms. When a molecule has two or more stereogenic centers, stereoisomers that are not mirror images can exist; these are called diastereoisomers. Within this general class, there are special types of stereoisomers that are always optically inactive and are called meso forms. Construct a model with four different colored balls about a carbon center. Construct another identical to the first and verify this by the superimposition test. Now remove the same colored balls, blue (C from...

PART 3: 2,3-BUTANEDIOL CH-CH(OH)-CH(OH)-CH, mirror images, not superimposable Build as many models of 2,3-butanediol as you can. First, attach two carbons with a single bond. To each carbon add one carbon, one hydrogen, and one oxygen. To complete the structure, Ti the remaining hydrogen atoms. Remember, a model is not different if it is completely superimposable on one already constructed! 13. How many stereochemically different models are possible for 2,3-butanediol? 14.
