Verified step by step guidance1
Identify the longest continuous carbon chain in the molecule. This will determine the base name of the compound, which is based on the number of carbon atoms in this chain.
Number the carbon atoms in the longest chain starting from the end nearest to the first substituent group. This ensures the lowest possible numbers for the substituents.
Identify and name the substituents attached to the main chain. Common substituents include methyl, ethyl, propyl, and isopropyl groups.
Assign numbers to the substituents based on their position on the main chain. Use the numbers from the numbering step to indicate the position of each substituent.
Combine the names of the substituents with the base name of the compound, arranging substituents alphabetically and using hyphens to separate numbers from names. Ensure the name reflects the correct positions and types of substituents.
