1. Carefully draw the line structures of all the stereoisomers of the compound using proper stereochemical notation. Any mirror images should be drawn side-by-side indicating the mirror plane. Structures should be drawn using the zig-zag style, either by hand or using ChemDraw (see note below).

2. Determine if the mirror images can be superimposed and therefore if they are enantiomers and/or diastereomers.

3. Identify the stereogenic centre(s) of the molecule (if applicable).

4. Determine the configuration at each stereogenic centre (R or S), if applicable.

5. If there are more than 2 stereoisomers, perform a full stereochemical analysis of your structures, indicating which pairs are enantiomers and/or diastereomers.
