What are alkyl aromatics?

What are alkyl aromatics?

From Wikipedia, the free encyclopedia. The alkylbenzenes are derivatives of benzene, in which one or more hydrogen atoms are replaced by alkyl groups of different sizes. They are a subset of the aromatic hydrocarbons. The simplest member is toluene, in which a hydrogen atom of the benzene was replaced by a methyl group …

What does aromatic mean in chemistry?

aromatic compound, any of a large class of unsaturated chemical compounds characterized by one or more planar rings of atoms joined by covalent bonds of two different kinds. The unique stability of these compounds is referred to as aromaticity.

What are arenes in chemistry?

Aromatic hydrocarbons, or arenes, are aromatic organic compounds containing solely carbon and hydrogen atoms. The configuration of six carbon atoms in aromatic compounds is called a “benzene ring”, after the simple aromatic compound benzene, or a phenyl group when part of a larger compound.

Which is aromatic compounds?

Aromatic compounds, also known as arenes or aromatics, are chemical compounds that contain conjugated planar ring systems with delocalized pi electron clouds instead of discrete alternating single and double bonds. Typical aromatic compounds are benzene and toluene.

What is alkyl benzene used for?

Linear Alkyl Benzene (LAB) is used as surfactant in dilute solutions for their cleaning properties. Linear alkyl benzene is derived from petroleum and is the major detergent being used today, because of its low cost. LAB is the basic raw material for production of most widely used detergent.

How do you find aromatic compounds?

For a compound to be considered aromatic, it must be flat, cyclic, and conjugated and it must obey Huckel’s rule. Huckel’s rule states that an aromatic compound must have pi electrons in the overlapping p orbitals in order to be aromatic (n in this formula represents any integer).

Why do we call aromatic compounds 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 are alkyl arenes?

Alkylarene means the alkyl groups are attached to the benzene ring. They have general structure: R-C6H5.

Why aromatic compounds are called arenes?

Arenes are aromatic hydrocarbons. Aromatic hydrocarbons (or sometimes called arenes or aryl hydrocarbon) are hydrocarbons with sigma bonds and delocalized π electrons between carbon atoms forming rings.

What are aromatic hydrocarbons give example?

Aromatic Hydrocarbons are especially stable, unsaturated cyclic compounds made primarily of hydrogen and carbon atoms. 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 difference between alkyl group and alkane?

Re: Alkane vs Alkyl An alkane is a saturated hydrocarbon, which means there are only carbon-carbon single bonds. The -ane part of the naming is what indicates that the hydrocarbon has only single bonds. Alkyls are the substituents in alkanes. When naming the substituent, the ending -ane is changed to -yl.

Does an alkyl group have aromatic rings?

This alkyl group can be a simple, branched or cyclic, but it does not have aromatic rings. Alkyl groups have only carbon and hydrogen atoms in their structure. The general formula for an alkyl group can be given as C nH 2n+1 which is different from the formula of an alkane, C nH 2n+2 with the loss of a hydrogen atom.

What is aryl in organic chemistry?

What is Aryl. An aryl group always contains an aromatic ring. Aryl group is a simple aromatic compound where one hydrogen atom is removed from the ring, allowing it to get attached to a carbon chain. The most common aromatic ring is benzene. All aryl groups are derived from benzene structures.

How do you name aromatic compounds in chemistry?

In general, to name an aromatic compound, you can follow these steps: Identify and name the parent. If it is not one of the common names, then use benzene. Identify and name the substituents. Number the ring to give the substituents the smallest possible number. Put the substituents alphabetically followed by the parent name.

What is the general formula for alkyl group?

The general formula for an alkyl group can be given as C nH 2n+1 which is different from the formula of an alkane, C nH 2n+2 with the loss of a hydrogen atom. Thus, alkyl groups are derived from alkanes.
