33 Chirality and stereoisomers What is chiral Chiral objects dont have an internal plane of symmetry aka a mirror plane of symmetry When superimposed chiral objects dont overlap perfectly.

Enantiomers and diastereomers are two types of stereoisomers. 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 compounds..
