"WebChiral centers are the most common features within molecules that give rise to chirality. Stereoisomer: A molecule that possesses at least one chiral center (or center of chirality). Enantiomers: A type of stereoisomer that exists in mirror image forms. See Figure 1. Diastereomers: A type of stereoisomer that possesses more than one chiral center.

WebApr 13, 2024 · Like molecules, solid crystals can exhibit mirror symmetry: the left and right forms are enantiomorphs. Enantiomorphism can occur even when the constituent molecules or ions are not chiral because they can pack together in a chiral pattern. Common quartz is a good example of a crystalline material with left and right enantiomorphs.
