- As a functional group, benzene, substituted benzenes and polybenzenes are called arenes. Nomenclature: Functional group suffix = -benzene (review) Functional group prefix = phenyl-. Substituted benzenes are usually named as such. The relative positions can be denoted as 1,2- = ortho-, 1,3- = meta- and 1,4- = para- substitution.

Benzene Derivatives in Organic Chemistry Click to enlarge. Benzene is a hugely important compound in organic chemistry. It consists of six carbon atoms joined together in a ring, with a hydrogen atom bonded to each carbon; by replacing one or more of these hydrogens with a functional group, a large number of different compounds can be formed.

- Lots of compounds in nature contain benzene units within larger structures. It is so common that it has gotten a great deal of attention over the years. These benzene units are sometimes called phenyls or, more generally, arenes. Benzene is a good example of a delocalized structure.It is something that could be studied using a Huckel MO approach. One of the pieces of experimental evidence that benzene has delocalized bonding comes from crystal structures.The first X-ray crystal structure of benzene was performed in 1929 by Kathleen Lonsdale.ots of compounds in nature contain benzene units within larger structures.

Phenol It is not to be confused with carbonic acid. Phenol, also known as carbolic acid, is an aromatic organic compound with the molecular formula C6H5OH. It is a white crystalline solid that is volatile. The molecule consists of a phenyl group (−C6H5) bonded to a hydroxyl group (−OH). It is mildly acidic and requires careful handling due to its propensity to cause chemical burns. Phenol was first extracted from coal tar, but today is produced on a large scale (about 7 billion kg/year) from petroleum.

- Benzene has 6 planar sp 2 carbons, and therefore each carbon has an unhybridized p orbital. These p orbitals are perfectly aligned for overlap (i.e. bonding, just like for a  bond). These p orbitals create a continuous ring of orbitals above and below the plane of the carbon atoms.h16 Aromatic Compounds (landscape).docx page 9 The lowest energy MO,  1, is entirely bonding, with zero nodes. All the lobes above the plane of carbon atoms interfere constructively, as do the lobes below the plane of carbon atoms. The six p orbitals overlap to form a continuously bonding ring of electron density.

- Aromatic hydrocarbons, or arenes, are those that have at least one benzene ring in them. A benzene ring is a ring of six carbon atoms with three double bonds. The formula for benzene, the simplest arene and base structure for all others, is C6H6. Any compound with a benzene ring is called an aromatic compound. There are many such compounds, which tend to be carcinogenic.

Benzene Benzene is an important organic chemical compound with the chemical formula C 6 H 6. Its molecule is composed of 6 carbon atoms joined in a ring, with 1 hydrogen atom attached to each carbon atom.enzene is used mainly as an intermediate to make other chemicals, above all ethylbenzene, cumene, cyclohexane, nitrobenzene, and alkylbenzene. More than half of the entire benzene production is processed into ethylbenzene, a precursor to styrene, which is used to make polymers and plastics like polystyrene and EPS.

Benzyl alcohol Benzyl alcohol. Benzyl alcohol is an aromatic alcohol with the formula C6H5CH2OH. The benzyl group is often abbreviated Bn (not to be confused with Bz which is used for benzoyl), thus benzyl alcohol is denoted as BnOH. Benzyl alcohol is a colorless liquid with a mild pleasant aromatic odor. It is a useful solvent due to its polarity, low toxicity, and low vapor pressure. Benzyl alcohol has moderate solubility in water (4 g/100 mL) and is miscible in alcohols and diethyl ether. The anion produced by deprotonation of the alcohol group is known as benzylate or benzyloxide

- Another factor increasing the stability of benzene is the bond angles between carbons. Recall that when it forms a double bond, the carbon atom's electron orbitals hybridize to form three sp2 orbitals, leaving one unhybridized 2p orbital.

- Effects of substituents on the acidity of phenols: Existence of electron attracting group, (for example-NO2, -X, - NR, -CN, -CHO, -COOH) on the benzene ring increases the acidity of phenol since it enables the ring to draw much more electrons from the phenoxy oxygen and so releasing easily the proton.

- Electrophilic substitution reactions involving positive ions Benzene and electrophiles Because of the delocalised electrons exposed above and below the plane of the rest of the molecule, benzene is obviously going to be highly attractive to electrophiles-species which seek after electron rich areas in other molecules.

- The actual bond length between each pair of adjacent carbons in the ring is 140 picometers. Thus, each pair of adjacent carbon atoms in benzene has the character of one and a half bonds rather than one or two bonds. To help illustrate this point, benzene is often drawn as a cyclohexane ring with a circle in the middle, which helps show the delocalization of the electrons in the double bonds.
