WebJun 18, 2014 · They are both the same thing. They are not. Stereocenters are merely atoms wherein the spatial arrangement of the bonding groups is such that exchanging any two groups results in the formation of a different stereoisomer. Chirality itself refers to the superposability of mirror images; for a chiral center, the mirror images of a particular ... Webatomic number of the atom that is bonded directly to the chiral center. The higher the atomic number, the higher the priority.! Number the four atoms, or groups of atoms, such that “1” has the highest priority and “4” has the lowest priority. 2. If two or more of the atoms that are bonded directly to the chiral center are the same, then WebStereocenter. A stereocenter, or stereogenic centre, is any atom in a molecule bearing groups such that an interchanging of any two groups leads to a stereoisomer [1]. In organic chemistry this usually refers to a carbon, phosphorus or sulfur atom, though it is also possible for other atoms to be stereocenters in organic and inorganic chemistry . phosphosphingolipids

"WebTherefore, lack of such a plane indicates a molecule is chiral. Compounds that contain a single stereo-center are always chiral. Some compounds that contain two or more stereocenters are achiral because of the symmetry of the relationship between the stereocenters.
