Sequence Rules for Assigning R/S Configuration
The Cahn-Ingold-Prelog (CIP) priority rules, also known as sequence rules, are used to assign the absolute configuration of chiral centers as R (rectus, right) or S (sinister, left). These rules provide a systematic method for ranking substituents attached to a chiral center to determine the spatial arrangement of the atoms or groups around it. 1. … Read more
