In [[organic chemistry]], hydrocarbons can be divided into '''aromatic compounds''' which contain '''aromatic rings''', also known as '''benzene rings''', and '''aliphatic compounds''' which do not.
An aromatic ring is a cylic arangement of six carbon atoms, in which delocalised electrons in the unused p-orbitals overlap to form a ring shaped bond above and below the planar ring, making it more stable than would be expected. The simplest aromatic compound is [[benzene]], which consists of exactly one aromatic ring and is thus more stable than would otherwise be expected.
Examples:
- Methane is an aliphatic compound, and contains no aromatic rings.
- Benzene is an aromatic compound, as it is an aromatic ring.
- Toluene is an aromatic compound, as it contains an aromatic ring bonded to a [[methyl]] group.
