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. WebMar 30, 2024 · 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.

WebExplanation: The cis-trans definition is unambiguous only when you have two different groups on one of the alkene carbons and the same two groups on the other carbon, as in but-2-ene. Then the two identical methyl groups are either cis or trans to each other, and the two identical hydrogen atoms are either cis or trans to each other.
