==Aromatic Compounds==

The most common aromatic compound( benzene) was first discorvered by micheal faraday who extracted the compound from a liquid residue obtained after heating whale oil to produce gas used to illuminate buildings. Chemists called the name pheno from the greek name phainein which means "to shine". The early scientist called it aromatic because of the pleasant smell, in this way we distinguish aromatic compoinds from aliphatuc which has higher number of hydrogen to carbon ratio.

Benzene is a cyclic compound with a cyclic cloud of delocalized electrons above and below the plane of the rings, due to this, all the c-c bond have the same length. This compound is also stable as a result of its resonance energy(36kcal/mol or 151kJ/mol)
