검증된 단계별 안내1
Identify the longest continuous carbon chain in the molecule. This chain will serve as the parent hydrocarbon and determines the base name (e.g., nonane, decane).
Number the longest chain from the end nearest to the first substituent to give the substituents the lowest possible numbers.
Identify and name all substituents attached to the main chain. In this molecule, look for alkyl groups such as methyl, isopropyl, or propyl groups.
Assign numbers to each substituent based on their position on the main chain according to the numbering established in step 2.
Combine the substituent names and their positions with the parent chain name to form the systematic name, listing substituents alphabetically and using prefixes (di-, tri-) if there are multiple identical substituents.
