WebR- and S- nomenclature of chirality centers. The Cahn-Ingold-Prelog priority rules are used for naming chirality centers ( i.e. R- and S- terminology) and geometric isomers ( i.e. E- or Z-alkenes) The rules are used to establish the priority of the groups attached to the chirality center (s) and are based on atomic number, and the first point ... WebThese two stereoisomers. They're a special type of stereoisomer that we call enantiomers. We'll talk much more about number of stereoisomers in a later video. The next video, we're going to go into more detail about chiral centers and chirality centers, and how to identify the number of chiral centers in a molecule. Up next: video.
