WebSep 5, 2024 · Chirality means handedness. It is exhibited by chiral molecules. They exist in pairs of stereoisomers. These are non-superimposable mirror images of each other. They do not have a plane of symmetry. They can rotate plane-polarized light and are optically active. Chirality is a property of molecules. WebThe meaning of CHIRAL is of or relating to a molecule that is not superimposable on its mirror image. How to use chiral in a sentence.
