Enantiomers include mirror images and non-superimposable chiral centers. Diastereomers contain non-superimposable chiral centers, but are not mirror images. Depending on the number of stereocenters, there could be far more than 2.

WebA chirality center is not the only possible cause of non-superimposable mirror images. However, for the purpose of this book, discussion is limited to chirality centers. The number of stereoisomers possible for any molecule can be calculated from the expression 2 n , where n is the number of chirality centers in the molecule.
