Verified step by step guidance1
Identify the longest carbon chain that contains the aldehyde group. In this structure, the longest chain has 7 carbon atoms, which corresponds to 'heptanal'.
Number the carbon chain starting from the end nearest to the aldehyde group, which is always given the number 1.
Identify and name the substituents attached to the main carbon chain. In this case, there is a fluorine atom on the fourth carbon and a methyl group on the fifth carbon.
Combine the names of the substituents with the main chain name, placing the substituents in alphabetical order and using their respective carbon numbers. The substituents are '4-fluoro' and '5-methyl'.
Construct the full name by combining the substituents and the main chain name: '4-fluoro-5-methylheptanal'.
