WebJul 20, 2024 · To use this naming system, we first decide which is the higher priority group on each carbon of the double bond, using the same priority rules that we learned for the R/S system. If the higher-priority groups are one the same side of the double bond, it is a Z -alkene, and if they are on the opposite side it is an E -alkene. WebLots of people mess up priorities when it comes to alkyl chains.
