Get Chapter 11 Arenes And Aromaticity - The Siva Group

Aromatic hydrocarbons (or sometimes called arenes or aryl hydrocarbon) are hydrocarbons with sigma bonds and delocalized π electrons between carbon atoms forming rings.

As a functional group, benzene, substituted benzenes and polybenzenes are called "arenes".

Aromatic rings (also known as aromatic compounds or arenes) are hydrocarbons which contain benzene, or some other related ring structure. Benzene, C6H6, is often drawn as a ring of six carbon atoms, with alternating double bonds and single bonds: This simple picture has some complications, however.

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 (see below). The arenes you are likely to encounter at this level are based on benzene rings.

The aromatic compounds or arenes are having the general formula of \[{C_n}{H_{2n - 6m}}\]where n is the number of atoms present and m is the number of rings. - Aromatic compounds will undergo nucleophilic and electrophilic reactions.

Aromatic hydrocarbons (arenes) A distinctive set of physical and chemical properties is imparted to molecules that contain a functional group composed of three pairs of doubly bonded atoms (usually all carbon atoms) bonded together in the shape of a regular planar (flat) hexagon.

major reference. These compounds are hydrocarbons that contain a benzene ring as a structural unit. In addition to benzene, other examples include and naphthalene.

The so-called aromatic hydrocarbons, or arenes, are cyclic unsaturated compounds that have such strikingly different chemical properties from conjugated alkenes (polyenes) that it is convenient to consider them as a separate class of hydrocarbon.

Huckel's Rule states that a Cyclic, Planar molecule is considered to be Aromatic if it has 4n + 2π Electrons.
