The benzene parent molecule is #C_6H_6#. It is a high symmetry hexagon, which belongs to the #D_(6h)# point group. How many ways can I arrange 2 heteroatoms around the hexagon for #C_6H_4X_2#?

Explanation:

It doesn't take too much insight to realize that I can position the halides #1,2# (with respect to each other), #1,3#, or #1,4# - 3 isomers of dibromobenzene are thus possible. I urge you to sit down with a pencil and paper to confirm that this is correct.
