##### 1 Answer

The benzene parent molecule is ${C}_{6} {H}_{6}$. It is a high symmetry hexagon, which belongs to the ${D}_{6 h}$ point group. How many ways can I arrange 2 heteroatoms around the hexagon for ${C}_{6} {H}_{4} {X}_{2}$?

#### 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.
