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. It refers to the whole molecule and not an atom.
