What is the importance of aromatic compounds?
Aromatic compounds are essential in industry; about 35 million tons of aromatic compounds are produced in the world every year to produce important chemicals and polymers, such as polyester and nylon. Aromatic compounds are also vital to the biochemistry of all living things.
What do you mean by aromatic compound?
Aromatic compounds are chemical compounds that consist of conjugated planar ring systems accompanied by delocalized pi-electron clouds in place of individual alternating double and single bonds. They are also called aromatics or arenes. The best examples are toluene and benzene.
What are the uses of aromatic hydrocarbons?
Aromatic hydrocarbons are non-polar and relatively non-reactive due to these resonance structures and make excellent solvents. They are used in manufacturing fuels, pesticides, lacquers, paints, detergents, and more. One important example of an aromatic hydrocarbon is benzene, a six-carbon ring structure.
What is the function of aromatic hydrocarbon?
Aromatic compounds are cyclic compounds in which all ring atoms participate in a network of π bonds, resulting in unusual stability. Aromatic compounds are less reactive than alkenes, making them useful industrial solvents for nonpolar compounds. Aromatic compounds are produced from petroleum and coal tar.
Why is aromatic hydrocarbon important?
Aromatic hydrocarbons including benzene, toluene, ethyl benzene, xylene (BTEX) are retrieved during fossil fuel extraction and used as solvents in consumer and industrial products, as gasoline additives, and as intermediates in the synthesis of organic compounds for many consumer products.
Why are aromatic compounds called aromatic?
Aromatic compounds, originally named because of their fragrant properties, are unsaturated hydrocarbon ring structures that exhibit special properties, including unusual stability, due to their aromaticity. They are often represented as resonance structures containing single and double bonds.
What is the purpose of benzene?
Benzene is a widely used industrial chemical. Benzene is found in crude oil and is a major part of gasoline. It’s used to make plastics, resins, synthetic fibers, rubber lubricants, dyes, detergents, drugs and pesticides. Benzene is produced naturally by volcanoes and forest fires.
What is characteristic of aromatic compounds?
Aromatic compounds are generally nonpolar and immiscible with water. As they are often unreactive, they are useful as solvents for other nonpolar compounds. Due to their high ratio of carbon to hydrogen, aromatic compounds are characterized by a sooty yellow flame.
What is the importance of aromatic hydrocarbons in biological systems processes?
Uses of Aromatic Hydrocarbons The green pigment found in plants, more commonly known as chlorophyll, consists of aromatic hydrocarbons and is very important in the process of food production in plants. The nucleic acids and amino acids in the human body also consist of these aromatic hydrocarbons.
What makes a compound an aromatic chemical compound?
In order for a compound to be classified as aromatic, it needs to follow the following criteria: The chemical structure must contain atoms bonded together to form a ring. The bonds in the ring should contain alternating double and single bonds. The ring must be coplanar; atoms in the ring must all be in the same plane.
Which is an example of an aromatic molecule?
The molecule should be planar or flat. Those compounds which follow the above 4 rules of aromaticity, they are generally flat as in that condition they possess large enough potential energy. Examples of Aromatic Compounds All aromatic compounds are hydrocarbons.
Where does the word aromaticity come from in chemistry?
The word aromaticity comes from the word ‘aroma’ which means fragrance or odor. Since most of the aromatic compounds are derivatives of benzene and benzene gives distinct odor so, the compounds were named as aromatic compounds. Although presently many non – benzene aromatic compounds have been discovered which do not have any odor.
What are the requirements for an aromatic compound?
Needless to say, aromatic compounds are vital to us in many aspects. The three general requirements for a compound to be aromatic are: Each element within the ring must have a p-orbital that is perpendicular to the ring, hence the molecule is planar. This means that the ring cannot contain a neutral sp 3 carbon.
