Definition: Nomenclature is a set of rational rules schemed by the international union of pure and applied chemistry (IUPAC) to bypass problems caused by arbitrary nomenclature. These are called terminal alkenes and because one of the carbons is connected to two hydrogens, they are not stereoisomeric, i. e. they cannot be cis or trans: Internal alkenes, on the other hand, can be cis or trans depending on the relative position of two identical alkyl groups on both carbons of the double bond. In the first example of naming alkenes, we used a molecule where the double bond was on the terminal position. Naming alkenes practice with answers pdf worksheet.
