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. WebThe rule of thumb is: chiral carbon centers are carbon atoms that are attached to four different substituents, that are placed at the corners of a tetrahedron.
