| Step | Action | Explanation & Example | | :--- | :--- | :--- | | | Identify the longest continuous chain of carbon atoms in the molecule. | Using the table above, this chain provides the base name (e.g., "heptane" for a 7-carbon chain). If there's a tie between chains of equal length, choose the one with the greatest number of substituents (branches). | | 2. Number the main chain | Count the carbon atoms from the end that gives the lowest possible number to the first substituent you encounter. | If the first branch is on carbon 2 from the right and carbon 3 from the left, choose the end that gives the branch carbon #2. If there's a tie, proceed to the next branch to find the lowest possible number. | | 3. Identify & name substituents | Identify all groups attached to the main chain that are not hydrogen atoms. | These are called alkyl groups . Their names are formed by changing the -ane ending of their parent alkane to -yl . For example, methyl (from methane), ethyl (from ethane), and propyl (from propane). | | 4. Assign numbers to substituents | Each substituent is assigned a number corresponding to the main-chain carbon atom it is attached to. | | | 5. Write the full name | - List the substituents in alphabetical order , ignoring number prefixes like di-, tri-, etc. | - Use commas to separate numbers (e.g., 2,3 ), and hyphens to separate numbers from words (e.g., 2-methyl ). | | | - Use the prefixes di-, tri-, tetra-, etc., for groups that appear more than once. | - Assemble the name as one continuous word: [Numbers]-[Substituent name][Parent chain name] | | | | Example: 4-ethyl-2-methylheptane |
