Verified step by step guidance1
Identify the longest carbon chain that contains the double bond. This will be the parent chain and will determine the base name of the alkene.
Number the carbon atoms in the parent chain starting from the end nearest to the double bond. This ensures the lowest possible numbers for the double bond.
Identify and name the substituents (side chains) attached to the parent chain. In this case, look for ethyl and isopropyl groups.
Assign a number to each substituent based on its position on the parent chain. Use the numbering from step 2 to determine these positions.
Combine the names and positions of the substituents with the base name of the alkene, ensuring to list substituents in alphabetical order and using hyphens to separate numbers from words.
