Answer
The alkene structure is shown in the picture below. It would be 4-ethyl-4-octene.
Work Step by Step
When ozonolysis takes place the double bond breaks and an oxygen is attached. Thus, while finding the starting molecule, the two parts with double bonded oxygens are joined to each other. When there is only one product after ozonolysis, the starting material is a ring. When there are two products formed, the starting material is a chain.
Since there are two products, the string material has to be a chain. Find the double bonded oxygens and join those carbons with a double bond.
