WebMar 26, 2016 · If a molecule has a chiral center that is designated R, the chiral center will be S in the molecule's enantiomer. You need to be able to assign whether a chiral center is R or S. To do so, you need to follow three steps: Number each of the substituents on the chiral center carbon using the Cahn–Ingold–Prelog system. WebR- and S- nomenclature of chirality centers The Cahn-Ingold-Prelog priority rules are used for naming chirality centers and geometric isomers (e.g. E- or Z-alkenes) These rules are used to establish the priority of the groups attached to the chirality center and are based on atomic number, and the first point of difference.
