Answer:
Aromatic compounds do have an aroma.
These compounds exhibit an unusual stability known as aromaticity, which can be understood using Hückel's rule. The term aromatic in chemistry is no longer associated with aroma, and many aromatic compounds have no smell.
The smell of a compound as we perceive it usually depends on which receptors in the nose will bind the molecule (or not). (There are exceptions for molecules that actually react with these receptors, such as HCl, but benzene and most aromatics are not one of these exceptions.)
These receptor, being proteins, are usually rather specific for certain shapes, not for bonding patterns. So chlorobenzene might fit into similar receptors as toluene which would lead to at least partly a similar smell, but that is it.
