The rule for naming is they all end with "benzene".
The general formula is CnH2n-6, n is the number of carbons is used to determine the number of hydrogen atoms. Example n=8, so H=(2(8)-6)=10
Naming Compounds- Again, ignore all the hydrogen's. We only worry about carbon atoms.
Rule #1-Name the benzene ring. End it with "benzene".
Rule #2-When necessary use the lowest number to give the locations of side chains that come off the benzene.
