Aromatic hydrocarbons are known as Arenes.
Hydrocarbons are the simplest organic compounds are composed of only two elements: carbon and hydrogen. They are classified into two—aliphatic and aromatic hydrocarbon.
They are hydrocarbons based on chains of C atoms. Alkanes are aliphatic hydrocarbons with only single covalent bonds. Alkenes are aliphatic hydrocarbons that contain at least one C–C double bond, and alkynes are aliphatic hydrocarbons that contain a C–C triple bond.
Benzene is an aromatic compound composed of six C atoms in a ring, alternating single and double C–C bonds. Aromatics are true hydrocarbons, meaning these molecules are made up of only hydrogen and carbon. There are many of these aromatic hydrocarbons in various fuels like gasoline, diesel and kerosene.
