WebIn 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.: 26 The purpose of the CIP system is to assign an R or S descriptor to each stereocenter and an E or Z descriptor … WebDec 10, 2024 · The benzene ring has the highest priority as it has another C connection after the C, C, C tie whereas the others only have hydrogen attached to them. Therefore the order of priorities is cycling counter clockwise which would mean that it is a S isomer.
