aromatic benzene


Compounds containing benzene rings (see above) are aromatic compounds. If there are other groups present on the benzene ring the compound is said to be a substituted benzene. The chemical properties of substituted benzenes are determined both by the aromatic groups and by the properties of the group bonded to the ring. In most instances, the presence of the benzene ring will not interfere with chemical tests (discussed later) for the groups bonded to the ring. For example, benzaldehyde, which contains both an aldehyde group and a benzene ring, would give positive tests for both an aromatic compound and for an aldehyde.

is benzaldehyde.
