Benzene is an aromatic hydrocarbon composed of six carbon atoms joined in a ring with one hydrogen atom attached to each.
Explanation:
The word aromaticity is used to represent a cyclic (ring-shaped), planar (flat) molecule with a ring of resonance links that shows more endurance than other geometric or connective patterns with the same set of atoms. Although, many non-benzene aromatic compounds survive.
The configuration of six carbon atoms in aromatic compounds is identified as a benzene ring, following the modest plausible such hydrocarbon, benzene.
