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. WebChirality essentially means 'mirror-image, non-superimposable molecules', and to say that a molecule is chiral is to say that its mirror image (it must have one) is not the same as it self. Whether a molecule is chiral or achiral depends upon a certain set of overlapping conditions.
The chirality of a molecule is based on the molecular symmetry of its conformations. A conformation of a molecule is chiral if and only if it belongs to the Cn, Dn, T, O, I point groups (the chiral point groups). However, whether the molecule itself is considered to be chiral depends on whether its chiral conformations are persistent isomers that could be isolated as separated enantiomers, at least in principle, or the enantiomeric conformers rapidly interconvert at a given t…
