Chirality handedness
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. WebCis and trans double bonds are sterogenic centers in that two different compounds are possible that are stereoisomers (diasteromers). However, that is not sufficient. You must …
