1. Find the longest carbon chain2. Circle the longest chain3. Number the chain starting at the

end with closest substituent4. Name the substituents5. Name the longest chain

Naming Rules

1. When two or more substituents are on the same carbon, use thenumber twice.

2. When two or more substituents are identical, use prefixes3. When two chains are the same length, use the one with the

most substituents on it.4. If substituents are at equall distances from the ends of the

chain, go to the next substituent.
