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. WebThe isomers are named using the E,Z system of nomenclature. The lone pair has the lowest priority.
