There are several aromatic compounds with the formula #C_8H_9Cl#. What are three that have a disubstituted ring where the chlorine is not attached to the ring?

They have to be the ortho/meta/para isomers. "Not attached to the ring" only means not directly attached. It does not mean you have a chlorine atom somewhere, floating freely next to the compound.
Ortho (same side) means a 1,2 relationship between two aromatic substituents, meta means 1,3, and para (opposite sides) means 1,4.
A default aromatic ring is benzene,
- We can have
#-"CH"_2"Cl"# as one substituent and#"CH"_3# as the other. This accounts for the remaining#"C"_2"H"_5# in the formula. - We can move one of substituents around for the isomers.
Convince yourself that the formulas are still
- o-chloromethyltoluene
- m-chloromethyltoluene
- p-chloromethyltoluene
