Think about these substances: mothballs and cinnamon. Both of these have a strong and unique smell. This is because these substances are made of aromatic compounds. In this lesson, we will learn all about aromatic compounds.
Let’s think of substances that have are fragrant or have distinct odor like perfume, vanilla and cinnamon. All these substances are known to have a distinct smell and are fragrant, or we can say aromatic. The smell is because these substances are made of aromatic compounds.

These Substances are Made of Aromatic Compounds
__Aromatic compounds__ are substances that consist of one or more rings in its chemical structure that contain alternating single and double bonds. For instance, benzene is an aromatic compound. The chemical structure of benzene, as illustrated below, contains a hexagon ring with alternating double bonds. Here, there are two ways to draw benzene. Structure 1 shows all the carbon (C) and hydrogen (H) atoms bonded together, and structure 2 shows a hexagon with alternating double bonds. In structure 2, the edges of the hexagon are the carbon atoms, and the hydrogen atoms are not shown.
Chemical Structure of Aromatic Compound: Benzene
Below are other examples of aromatic compounds, toluene and naphthalene. Here, we can see that they contain rings with alternating single and double bonds in their chemical structure.
Examples of Aromatic Compounds
In the ring, the electrons are delocalized. When we say ‘’delocalized electrons’’, it means that these electrons are not attached on a fixed atom. The electrons are spread out over the ring, and they can also be described as “floatin...

- Discussion: The synthesised ethyl cinnamate weighed 0.56 g, which was equivalent to 140% of the theoretical yield of 0.414 g. This excessive yield was resultant of the impurities within the product, where the solvents, particularly the dichloromethane, were not sufficiently removed from the product. In figure 3, the peak at 5.22 ppm with a normalised intensity of 1.00 evidenced the significant proportion of the dichloromethane in the product, and the peak at 0.88 ppm with a normalised intensity of 0.25 indicated some remaining hexane.4 The unreasonable yield was mostly attributed to these....

- Flame-retardant compounds are designed to decrease the flammability of polymeric materials but in many cases the presence of flame retardants in the polymeric materials increases smoke production and toxicity of degradation products. Smoke evolution and the degradation products, either particulate or gaseous is an important aspect of fire hazard. Smoke is defined as a cloud of particles individually invisible but due to light scattering and/or absorption of light, the particles appear opaque. It occurs due to incomplete combustion of the polymeric materials.... [tags: combustion, cotton, decomposition]

- What are organic compounds, you may ask. Well organic compounds are compounds that always contain carbon, or any compound that contains a carbon atom. But some describe organic compounds as any of a large class of chemical compounds in which one or more atoms of carbon are covalently linked to atoms of other elements, most commonly are hydrogen, oxygen, and nitrogen. But there are a few exceptions to this organic rule, which are carbon monoxide, carbonates, carbon dioxide, cyanides, cyanates, carbides, and thyocyanates, which are all considered inorganic....

- The whole world is made up of Chemical and Physical bonds and one of the greatest advancements in history is understanding the way atoms connect together to form compounds. In chemical bonding there are two types of bonds that are called Ionic and Covalent bonds. Ionic bonds form when an electrical attraction between two oppositely charged atoms or groups of atoms called Ions. Covalent bonds form when one or more electrons are transferred from one atom to another. Atoms either share pairs of electrons between them or transfer one or more electrons from one atom to another.... [tags: compounds, chemical bonding, atoms]

- For over two thousand years, people have been cultivating and consuming Asparagus officinalis. During this time some people have observed a peculiar manifestation of an odd odor in their urine shortly after ingesting this vegetable (Mitchel and Waring 2014). This particular stench has been described as smelling like boiled cabbage (Mitchel et al. 1987, Pelchat et al. 2011). Many experiments have contributed this smell to sulfurous molecules found in the urine after asparagus ingestion, the most common molecules found being methanethiol and dimethyl sulfide (Lison et al....

- !!!What Is A Chemical Formula. Everyday, we encounter chemical substances. In our household alone, substances that we use to clean, and those that are staples in our medicine cabinet, as shown in the picture below, are made up of chemical substances. These chemicals that we use everyday are made up of atoms of a fixed proportion and these atoms are arranged in a certain way. How do we know what the atoms are, their proportion as well as their arrangement. This information can be gathered from the chemical formula of the substance....

- ... This works because electrons in atoms can only exist in particular energy levels. An electron moves from a lower to a higher energy level by absorbing electromagnetic radiation. An electron will also emit radiation as it drops from a higher energy level to a lower one. Each element's electrons emits and absorbs specific frequencies of radiation and it is this that allows individual elements to be determined, even when other elements are present. AAS is able to measure extremely small concentrations of elements, such as parts per million (ppm) and occasionally parts per billion (ppb).... [tags: cereal, inorganic, material chemist]

- Mentha arvensis (MA) commonaly known as Mint or Pudina, belongs to family Lamiaceae. It is aromatic herb traditionally used as antiseptic, anthelmintic, diuretic, digestive, expectorent and cardio tonic. In current study, in vitro cytotoxic activity of crude whole plant extracts of Mentha arvensis was evaluated by Sulforhodamine B assay on three human cancer cell-lines of different tissues i.e. A-549(lung), MCF-7(breast) and COLO-205 (colon). Methanol extract of Mentha arvensis was observed to be significantly more cytotoxic in dose dependent manner than Petroleum ether extract of Mentha arvensis with IC50 ranging from 120-165 µg/ml for chosen cell lines....

- Water is the most abundant, most accessible and one of the most studied chemical compounds. The fact that it is located throughout the planet, its crucial importance to man 's survival and its ability to exist in solid, liquid and vapour phases and transform between them readily has made this liquid uppermost in the thinking of man throughout time (Gelder., 2012). The name water typically refers to the liquid state of the compound. The solid phase is known as ice and gas phase is called steam. Water’s chemical name is identified by the name of Dihydrogen monoxide (Helmenstine, 2016).... [tags: Water, Evaporation, Water cycle, Hydrology]
