- Draw the lines 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.

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

- Identify the stereogenic centre(s) of the molecule (if applicable), and determine the configuration at each stereogenic centre (R or S).

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