What are ..arenes..Arenes are aromatic hydrocarbons. The term "aromatic" originally referred to their pleasant smells (e.g., from cinnamon bark, wintergreen leaves, vanilla beans and anise seeds), but now implies a particular sort of delocalized bonding. Aromatic hydrocarbons (or sometimes called arenes or aryl hydrocarbon) are hydrocarbons with sigma bonds and delocalized π

An arene or aromatic hydrocarbon is a hydrocarbon with alternating double and single bonds between carbon atoms forming rings. Arenes are aromatic hydrocarbons. The term "aromatic" originally referred to the pleasant smells given off by arenes, but now implies a particular type of delocalized bonding.
Example of Arene are: benzene, toluene,phenol etc.
They are classified on the basis of number of fused ring present in molecule.
Their general formula is: CnH2n−6m where n=number of carbon and m=number of rings.
Monocyclic arene-1 ring is present. Example toluene, benzene.
Polycyclic arene- when more than 1 rings are present. Example –Napthalene, anthracene.
