Cyclohexene can be named using the E/Z configuration based on the arrangement of substituents around the double bond. For cyclohexene, which is symmetric with respect to the double bond, the priority of the attached atoms is determined by comparing the two groups on each carbon of the double bond. If the higher priority groups are on the same side, the configuration is designated as Z (from "Zame" side). Conversely, if they are on opposite sides, it is labeled as E. However, it is noted that E-cyclohexene is unlikely to occur in practice due to steric factors when only carbon and hydrogen are present. This mnemonic aids in remembering the naming convention.
