Question: What Is Another Name For Aromatic Hydrocarbon?

How do hydrocarbons affect human health?

Gasoline, kerosene, lamp oil and furniture oil are all examples of hydrocarbons.

If someone accidentally drinks a hydrocarbon product and it enters the lungs, breathing problems can develop.

Some hydrocarbons can cause other effects, including coma, seizures, irregular heart rhythms or damage to the kidneys or liver..

What are examples of aromatic hydrocarbons?

Aromatic hydrocarbons are especially stable because they are both cyclic and unsaturated. The electrons that create the double bonds are delocalized and can move between parent atoms. Examples of aromatic hydrocarbons include benzene, toluene, purines and pyrimidines.

What is the functional group of aromatic hydrocarbons?

An aromatic functional group or other substituent is called an aryl group. The earliest use of the term aromatic was in an article by August Wilhelm Hofmann in 1855. Hofmann used the term for a class of benzene compounds, many of which have odors (aromas), unlike pure saturated hydrocarbons.

What structure do all aromatic hydrocarbons have in common?

The configuration of six carbon atoms in aromatic compounds is called a “benzene ring”, after the simplest possible such hydrocarbon, benzene. Aromatic hydrocarbons can be monocyclic (MAH) or polycyclic (PAH).

Do hydrocarbons cause cancer?

Polycyclic aromatic hydrocarbons (PAHs) are made whenever substances are burned. PAHs are also found at former coal-gasification sites. Breathing smoke or coming into contact with contaminated soil exposes people to PAHs. Some PAHs may cause cancer and may affect the eyes, kidneys, and liver.

What is the name of the simplest aromatic hydrocarbon?

BenzeneBenzene ring model Benzene, C6H6, is the simplest aromatic hydrocarbon and was recognized as the first aromatic hydrocarbon, with the nature of its bonding first being recognized by Kekulé in the 19th century. Each carbon atom in the hexagonal cycle has four electrons to share.

What are the main sources of aromatic hydrocarbons?

Simple aromatic hydrocarbons come from two main sources: Coal and petroleum. Coal is a complex mixture of a large number of compounds, most of which are long-chain compounds. If coal is heated to about 1000 °C in the absence of air (oxygen), volatile components, the so-called tar oil, are stripped out.

Why are aromatic hydrocarbons dangerous?

Long-term exposure to low levels of some PAHs have caused cancer in laboratory animals. Benzo(a)pyrene is the most common PAH to cause cancer in animals. Studies of workers exposed to mixtures of PAHs and other compounds have noted an increased risk of skin, lung, bladder, and gastrointestinal cancers.

What are the properties of aromatic hydrocarbon?

aromatic hydrocarbon: A compound having a closed ring of alternate single and double bonds with delocalized electrons. aromaticity: The property of organic compounds that have at least one conjugated ring of alternate single and double bonds, and exhibit extreme stability.

Are alkanes soluble in water?

Solubility. Alkanes (both alkanes and cycloalkanes) are virtually insoluble in water, but dissolve in organic solvents. However, liquid alkanes are good solvents for many other non-ionic organic compounds.

What are the common aromatic hydrocarbon and their importance?

Aromatic Hydrocarbons are circularly structured organic compounds that contain sigma bonds along with delocalized pi electrons. They are also referred to as arenes or aryl hydrocarbons. A few examples of aromatic hydrocarbons are provided below. It can be observed that all these compounds contain a benzene ring.

Which one is an aromatic hydrocarbon?

An aromatic hydrocarbon is a cyclic hydrocarbon with alternating double and single bonds and (4n + 2) π electrons. The most common example is benzene (n = 1). Aromatic hydrocarbons are much more stable than their noncyclic counterparts are. The carbon-carbon bonds in aromatic hydrocarbons are equivalent.

What is the most important aromatic compound?

BenzeneBenzene (C6H6) is the best-known aromatic compound and the parent to which numerous other aromatic compounds are related. The six carbons of benzene are joined in a ring, having the planar geometry of a regular hexagon in which all of the C—C bond distances are equal.

Why are they called aromatic hydrocarbons?

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 are some examples of aromatic compounds?

Polycyclic aromatic hydrocarbons are molecules containing two or more simple aromatic rings fused together by sharing two neighboring carbon atoms (see also simple aromatic rings). Examples are naphthalene, anthracene, and phenanthrene.

What are monocyclic aromatic hydrocarbons?

For monocyclic aromatic hydrocarbon, its molecule contains only one benzene ring, such as toluene, xylene, ethylbenzene, styrene, benzene and acetylene. Polycyclic aromatic hydrocarbon contains two or more benzene rings.
