Lone pairs of electrons are … WebApr 7, 2024 · Hint: Cahn- Ingold- Prelog sequence rules generally deal with the concept of the atomic number of the atoms. These rules are used in organic chemistry to name a stereoisomer of a molecule. The main purpose of these rules is to assign a R/S descriptor to each stereocenter, so that the molecule can be named uniquely.

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…
