WebJul 18, 2024 · R/S system of nomenclature is a naming system used for assigning absolute configuration to chiral molecules. R, Latin ‘ Rectus ‘ meaning right, and S, Latin ‘ Sinister’ meaning left. On a priority basis, branches of a chiral molecule are assigned numbers, and in decreasing trend, molecules are either named R, or S configured.
