A List of Aromatic Compounds Examples
Before we explore the aromatic compounds examples, we really need to understand what aromatic compounds are. Aromatic compounds are simply any compound related to benzene. However, in other cases, some compounds will be termed aromatic even when they have no element of benzene in them. There are several aromatic compounds in existence.
The Aromatic Compounds Examples
The simplest example of an aromatic compound is pyridine, C5H5N. It bears a great similarity with benzene in terms of its structure.

There are some aromatic compounds which have a heteroatom. They have an element other than the usual C and H and they have a five-member ring as well.
It is important to find out what these two elements have in common with pyredine and benzene that gives them their aromatic properties. These two compounds contain two double bonds. Hence, there are 4 p orbital electrons that are rightly perpendicular to the ring of the compound.

There are 6 electrons in these p orbital electrons. In analyzing the proper orientation of lone pairs, we find out that electrons are not in any way part of the loop of electrons. This is a principle characteristic of the aromatic compounds.
The figure of Aromatic Compounds Examples
The figure below shows the bonding and also the unbonded p optical electrons in pyrrole, pyredine and furan. There is a clear pattern here which we may be able to see. There is a loop of 6 electrons that is actually overlapping the p orbitals. Hence we may be tempted to qualify as a condition for aromaticity. However, we should also consider other forms of structures as well.

Huckel’s Rule is also very important in determining aromaticity in any type of compound. The rule says that the number of electrons in an aromatic compound should be 4n+2, where n is a whole number. The other rule is that there should be a planar array of electrons that is cyclic in nature. The examples above include compounds where 6 electrons are delocalized over the other 5 orbitals.
The first group of Aromatic Compounds Examples
The first group that contributes to the aromatic compounds examples is the mono-substituted compounds which include nitrobenzene, chlorobenzene, bromobenzene, toluene, cumene, aniline, phenol, anisole, benzoic acid, benzelsunifonic acid, benzaldehyde, benzonitrile, acetophenone and styrene. They possess some little variation in their structures but they are allderivatives of benzene.

The second group is that of the disubstituted compounds. These are actually the derivatives of benzene but they have special names. In other cases, isomers are possible. They have very special designations that have been adapted by the IUPAC for the sake of world uniformity. They include 1,2-disubstituted ortho, o-dichlorobenzene, o-nitrotoluene, 1,3-disubstituted meta, m-dibromobenzene, m-chlorophenol, 1,4-disubstituted para, p-fluoroni tr obenzene and p-nitroaniline.
The last group of Aromatic Compounds Examples
The last group of these aromatic compounds consists of the more highly substituted compounds which have more than two substituents. The substituent of carbon that normally corresponds to the special name of the compound is assigned the number 1. This assists in ensuring that proper alphabetical order is observed. Examples of these aromatic compounds include 2,4,6-trinitrophenol, 2,4,6-trinitrotoluene and 4-hydroxy-3-methoxybenzaldehyde.

An All-inclusive List of Aromatic Compounds Examples
There are several ways of classifying aromatic compounds examples due to the different forms of reactions and bonding involved in order for them to be formed. However, they all bear the same end characteristics that are possessed by aromatic compounds. For instance, we have the polyaromatic hydrocarbons. They are referred to as polycyclic aromatic hydrocarbons or the polynuclear aromatic hydrocarbons. They are atmospheric pollutants and contain no heteroatoms, neither do they carry any substituents. Naphthalene is one such example which is known to occur in oil, coal and tar deposits which are normally produced as of the burning fuel.

Contents of polyaromatic compounds have also been found in cooked foods such as meat cooked in very temperatures such as grilling, barbecuing or even the smoked fish. An exhaustive list of these compounds consists of acenaphthene, acenaphthylene, anthracene, benz(a)anthracene, benzo(a)pyrene, benzo(e)pyrene, benzo(b)fluoroanthene, benzo(ghi)perylene, benzo(i)fluoroanthene, benzo(k)fluoranthene, chrysene, dibenz(a, h)anthracene, fluoranthene, fluorine, indeno(1,2,3-cd)pyrene, phenanthrene and pyrene.

There are some aromatic compounds classified above that may be dangerous to human health. However, these could generally be very few because aromatic compounds form the major content of an endless list of aromatic plants and herbs. These produce a pleasant aroma that is used to freshen the air and purify the environment. Many of them are also used to cure many human complexities such as headaches, cardiovascular problems, nausea and many others.
The list of Aromatic Compounds Examples
The list containing aromatic compounds examples is simply endless. Others include neophyl chloride, nitrosobenzene, vanillin, deltic acid, cycrimine, irone, isovanillin, hydramethylnon, carbazole, carbenicillin, bromoanisole, benzylamine, graphene, halogenoarene, thyroxine, transfluthrin, trichlorobenzene, thyrene oxide, resmethrin, phenacylphenformin, phenyl azide, diarylethene, aloin, anethole, aspartame, biperidin, bromobenzene, bromoanisole, triphos, usnic acid, irone, pargyline, cupferron among others. It is important to have a glimpse of the aromatic compounds examples because it will help you to identify the difference between those that are toxic and those that can be used as drugs.
