Naming Rules
1. Find the longest carbon chain
2. Circle the longest chain
3. Number the chain starting at the
end with closest substituent
4. Name the substituents
5. Name the longest chain
Naming Tips
1. When two or more substituents are on the same carbon, use the
number twice.
2. When two or more substituents are identical, use prefixes
3. 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.
