An aromatic hydrocarbon (abbreviated as ah) or arene  (or sometimes aryl hydrocarbon) is a hydrocarbon with a conjugated cyclic molecular structure that is much more stable than the hypothetical localized structure aromatic hydrocarbons can be monocyclic or polycyclic. Aromatic hydrocarbons have at least 6 number of carbon atoms along with double bonds in the form of a ring structure this 6-carbon structure in the aromatic hydrocarbons is called as benzene ringthe other name for these compounds is 'arenes. Aromatic hydrocarbons, which consist of closed rings of carbon atoms the building block of aromatic hydrocarbons is the benzene ring the arrangement of atoms is shown on the left the version in the center is often used to simplify diagrams of molecular structures.

Aromatic hydrocarbons have formulas that can be drawn as cyclic alkenes, making them appear unsaturated, but their structure and properties are generally quite different, so they are not considered to be alkenes aromatic compounds serve as the basis for many drugs, antiseptics, explosives.

Aromatic hydrocarbons are those which contain one or more benzene rings symbolic structures of some common aromatic hydrocarbons are shown below those hydrocarbons which do not contain a benzine ring are called aliphatic hydrocarbons. An aromatic hydrocarbon, or arene, is a hydrocarbon ring compound it has alternating double and single bonds between carbon atoms forming rings many of the compounds have a sweet scent, hence the term 'aromatic.

Introduction to aromatic hydrocarbons james richard fromm when a double bond replaces one of the single carbon-carbon bonds in cyclohexane, the double bond behaves just as a single bond in hexene or any other alkene introduction of a second double bond on a non-adjacent carbon gives.
Hydrocarbon - polymerization: a single alkene molecule, called a monomer, can add to the double bond of another to give a product, called a dimer, having twice the molecular weight in the presence of an acid catalyst, the monomer 2-methylpropene (c4h8), for example, is converted to a mixture of.
