WebA chirality center (chiral center) is a type of stereocenter. A chirality center is defined as an atom holding a set of four different ligands (atoms or groups of atoms) in a spatial arrangement which is non-superposable on its mirror image. Chirality centers must be sp 3 hybridized, meaning that a chirality center can only have single bonds. WebNov 19, 2014 · A chiral centre is an atom that has four different groups bonded to it in such a manner that it has a nonsuperimposable mirror image.
