WebNOMENCLATURE OF ALKENES. 1. Identify longest continuous carbon chain that includes the alkene. 2. Number to give the alkene the lowest possible number. 3. Use -ene suffix at the end of the parent chain and appropriate chain locator. 4. Assign cis/trans or E/Z to any alkenes that can exhibit cis/trans isomerism. WebThe guidelines for assigning group priority in E/Z naming system. 1. Priority is assigned based on the atomic number of the atoms bonded directly to the sp2 double bond carbon – the larger the atomic number, the higher the priority (isotopes with a higher mass number have higher priority).
