Chiral Center, chiral atom, chirality center, or center of chirality is a tetrahedral atom in a molecule bearing four different ligands, with lone pairs, if any, treated as ligands. If a chiral center is a carbon atom, it can also be called an asymmetric carbon atom. Thus, in eg. 1 the chiral center is an asymmetric carbon atom.
