WebSo basically, Z is just a fancy way of saying cis with three or more substituents. E is a fancy way of saying trans with 3 or more substituents. Using the periodic table to assign priorities, trans = E, and cis = Z . Example #1: Assign an (E) – (Z) designation to the following alkenes if applicable.
