Aromatic hydrocarbons nomenclature

We follow the 1979 IUPAC recommendations summarized in Polynuclear Aromatic Hydrocarbons Nomenclature Guide (Loening et al. 1990). The American Chemical Society also publishes the Ring Systems Handbook, which, ca. 1990, contained structural diagrams for over 70,000 unique ring systems (American Chemical Society, 1977 to present).

Benzene derivatives. Tbe nomenclature is a combination of the lUPAC system and traditional names. Many of the derivatives are named by the substituent group appearing as the prefbt. These may be considered a subclass of the aliphatic-aromatic hydrocarbon family, which contains both aliphatic and aromatic units in its structures. Thus, alkylbenzenes are made up of a benzene ring and alkane units alkenylbenzenes are Composed of a benzene ring and alkene units and alkynylbenzenes comprise a benzene ring and alkyne units. Examples of alkylbenzenes include... 

The fuel oils coming out of olefin plants are also characterized by an abundance of polynuclear aromatic molecules, (Same definition as for Figure 2—1). They are sometimes inaccurately referred to as having a high aromatics content. Nomenclature aside, because of this, the burning characteristics of pyrolysis gas oil and pyrolysis pitch are poor. They are smoky, sooty, and gum formers they rend to be more viscous, and because of their polynuclear aromatic concent, they are suspected carcinogens. They are basically a witchs brew of unsavory hydrocarbons.. ... 

Over the years, many people contributed to the development of the field of organic chemistry. To better understand how this science provides so many useful items for our daily use, it is necessary to be familiar with some of the nomenclature of organic chemistry. There are two basic types of hydrocarbon substances, namely, aliphatic and aromatic. There are three basic types of aliphatic hydrocarbon molecules defined by the number of bonds involved in straight linear-chained molecules. If the basic structure of a hydrocarbon molecule is a ring instead of a straight chain, they are known as aromatic hydrocarbons, typified by the benzene ring.

Two systems (246,247) will be discussed in this subsection. The nomenclature of these compounds, as of other borazaromatics, has been a point of controversy. Whereas the authors in this field generally followed the procedure of naming these compounds after the isoconjugate parent aromatic hydrocarbon with prefixes like bora and aza indicating the replacement of a methine group by these atoms, in Chemical Abstracts the principal names are derived by reference to the azaborine system. In this Section and in Section...

We will use preferentially the current IUPAC nomenclature. On replacing a carbon atom in an aromatic hydrocarbon by a heteroatom, one can name the resulting system by combining the heteroatom s name (using the suffix a for the heteroatom) with the name of the hydrocarbon, e.g., pyridine may be called azabenzene. However, on replacing a heteroatom by another one, the new heteroatom s name...

In I.U.P.A.C. nomenclature, the group—C5H5 derived by removing one hydrogen from benzene, is called the phenyl group. An aromatic hydrocarbon with an aliphatic side chain is named as a phenyl substituted hydrocarbon. Eor example ... 

Solution This problem requires a knowledge of arene nomenclature. Benzene (CeHe) is the simplest aromatic hydrocarbon. Benzene compounds can be named as a derivative of benzene or as a phenyl-substituted compound.
