The IUPAC naming of compounds follow a set of rules. First, find the longest carbon chain and the number of them. As shown in the picture, the more long chain of 9 carbon atoms. In the 3rd and 5th carbon atoms, there is one double bond for each one. Thus, the parent chain is named as 3,5 - nonadiene, 'di' because there are two double bonds. On the other hand, in the 5th carbon, there is a branching of the chain of two carbons (ethyl). Therefore, its IUPAC name is (3e,5z)-5-ethyl-3,5-nonadiene.
