WebJan 28, 2015 · 1. Chirality - Stereocenter Chirality - is a definition that refers to the molecule that cannot be superimposed on its mirror image. A simple example of chirality is "hand model", one hand is the mirror image of the other hand, and they cannot be superimposed. The word chirality is derived from the Greek (kheir - hand). A chiral phenomenon is one that is not identical to its mirror image (see the article on mathematical chirality). The spin of a particle may be used to define a handedness, or helicity, for that particle, which, in the case of a massless particle, is the same as chirality. A symmetry transformation between the two is called … See more The helicity of a particle is positive (“right-handed”) if the direction of its spin is the same as the direction of its motion. It is negative (“left-handed”) if the directions of spin and motion are opposite.

Stereoisomers are isomers that differ in the spatial arrangement of atoms, rather than the order of atomic connectivity. One of the most interesting types of isomer is mirror-image stereoisomers, a non-superimposable set of two molecules that are mirror images of one another.
