Hydrocarbons are compounds of hydrogen and carbon. Below ordinary circumstances some of the hydrocarbons are gases, others are liquids and still others are solids. Propane, kerosene, gasoline, lubricating oils, paraffin and Vaseline all are hydrocarbons. Other hydrocarbons work as the raw material with regard to dyes, medicines and other end products. Paraffin Hydrocarbons - A combination of some of the solid compounds of this collection. Paraffin hydrocarbons fulfill the general formula CnH2n+2.
The lower carbon compounds of this series, including ethane, methane, butane and propane, are gases under normal conditions. Compounds with 5 to 16 carbon atoms are liquids and those materials that contain greater than 16 carbon atoms are solid at ordinary circumstances. Paraffin hydrocarbons are also referred to as saturated hydrocarbons. Aromatic Hydrocarbons - Hydrocarbons characterized through a molecular structure with six carbon atom rings. The solvents benzene, xylene, toluene, naphthalene and so on. are all typical aromatic hydrocarbons.
An aromatic hydrocarbon or aryl hydrocarbon (or occasionally arene) is a hydrocarbon characterized by general changing single and double bonds among carbons. The word 'aromatic' had been assigned prior to the physical mechanism determining aromaticity has been discovered and was derived from the fact that most of the compounds possess a sweet scent. The settings of six carbon atoms in aromatic compounds is referred to as a benzene ring, after the simplest possible such hydrocarbon, benzene. Aromatic hydrocarbons could be polycyclic (PAH) or monocyclic (MAH).
Several non-benzene-based compounds known as heteroarenes, which stick to Hückel's rule, are also aromatic compounds. In these compounds, a minimum of one carbon atom is changed by one of the heteroatoms oxygen, sulfur or nitrogen. Samples of non-benzene compounds with aromatic properties are furan, a heterocyclic compound having a five-membered ring that contains an oxygen atom and pyridine, a heterocyclic compound with a six-membered ring made up of one nitrogen atom.
list of aromatic hydrocarbons
Hydrocarbons are the most basic organic compounds. Containing just hydrogen and carbon, they could be branched chain, straight-chain or cyclic molecules. Carbon tends to make four bonds in a tetrahedral geometry. Hydrocarbon derivatives are created when there is a substitution of a functional group at a number of these positions.
Here are some common hydrocarbons:
