Work Step by Step
1. Identify and count the carbons on the largest chain, giving the appropriate name.
2. Number the chain in a way to get the lowest numbers for the substituents.
3. Name and name the substituents.
4. Add the name of the main chain at the end, with the appropriate prefix.
Note: in b and d, the number of the substituent is not necessary because it can only be in one position.
