For 10 points, name this property, a molecule's lack of a plane of symmetry and hence possession of non-superimposable mirror images, with a name from the Greek for "handedness."
P/M notation is used to classify biaryl compounds that display the axial version of this property. Substances with this property are named according to the Cahn-Ingold-Prelog rules, and meso compounds notably lack this property, whose occurrence in thalidomide caused birth defects in thousands of children around the world. First observed by Pasteur in tartaric acid, it is associated with optical activity, leading to rotation of plane-polarized light.
