The IUPAC name of α–Farnesene including the stereochemistry is to be given. Concept introduction: The longest carbon chain containing the double bond to be chosen. Based on the name of the parent compound–the alkene name ends with the suffix–ene. The chain is to be numbered from the end that gives the lowest number to the carbon in double bond. Substituents are to be numbered according to their positions in the chain and listed alphabetically. The position of the double bond is indicated by giving the number of the first alkene carbon before the name of the parent name. If more than one double bond is present, their positions are indicated with the suffixes -diene, -triene and so on. The isomer that has the higher ranked groups on each carbon are on the same side of the double bond is said to have Z configuration. If the higher ranked groups are on opposite sides, the alkene is said to have E configuration. To give: The IUPAC name of Î±-farnesene including the stereochemistry.
