In organic chemistry, the Cahn–Ingold–Prelog (CIP) sequence rules (also the CIP priority convention; named for R.S. Cahn, C.K. Ingold, and Vladimir Prelog) are a standard process to completely and unequivocally name a stereoisomer of a molecule. The purpose of the CIP system is to assign an R or S descriptor to each stereocenter and an E or Z descriptor to each double bond so that the configuration of the entire molecule can be specified uniquely by including the descripto… Webb17 aug. 2024 · Cahn Ingold Prelog (CIP) rules assign the R and S nomenclature configuration to compounds with one stereocenter and E and Z nomenclature to double bonds. This way entire molecules can be uniquely specified by including R/S and E/Z descriptors to the IUPAC nomenclature.
