E and z system of nomenclature

WebThus E stands for opposite side and Z for the same side. For example. Generally cis isomer is said to be Z form and trans isomer is said to be E forms but due to sequence rule there are some exception. For example, 1,2 dichloro – 1 – bromoethene. Although CI atom present on opposite side but according to sequence rule it is Z form. WebE-Z Nomenclature for Geometrical Isomers . E-Z notation is used to name geometric isomers. It is an extension of cis-trans isomer. When none or most of the groups attached to the double bond are not same then in IUPAC system geometric isomers are notified or named with E or Z. E-Z is based on the cahn-ingold-prelog system.

What is E and Z configuration in organic chemistry? [Facts!]

WebE–Z notation can be used to describe the configuration of a double bond with two or more substituents.To do so, each substituent is assigned a priority using the Cahn–Ingold–Prelog rules.
