KIMIA hydrocarbons

KIMIA 

hydrocarbons


I am posting today in chemical subjects meterinya hydrocarbons
In chemistry, a hydrocarbon is a compound composed of the elements carbon (C) and hydrogen atoms (H). The entire chain hydrocarbons having carbon and hydrogen atoms bonded to the chain. The term is used also as a sense of aliphatic hydrocarbons.
For example, methane (swamp gas) is a hydrocarbon with one carbon atom and four hydrogen atoms: CH4. Ethane is a hydrocarbon (more specifically, an alkane) consisting of two carbon atoms are united by a single bond, each of which binds to three carbon atoms: C2H6. Propane has three C atoms (C3H8) and beyond (CnH2 • n +2).
Types of hydrocarbons
Classification of hydrocarbons, which are grouped by organic nomenclature is:
1. Hydrocarbon saturated / saturated (alkanes) are the simplest hydrocarbon. Hydrocarbons is composed entirely of a single bond and bound with hydrogen. The general formula for saturated hydrocarbons is CnH2n +2. [1] is the main composition of saturated hydrocarbons in fossil fuels and is found in the form of straight or branched chain. Hydrocarbons with the same molecular formula but different structural formulas called structural isomers. [2]
2. Unsaturated hydrocarbons / is not saturated hydrocarbons which have one or more double bonds, either duplicate or triplicate. Hydrocarbons having double bonds called alkenes, with the general formula CnH2n. [3] hydrocarbons that have a triple bond are called alkynes, with general formula CnH2n-2. [4]
3. Cycloalkanes are hydrocarbons containing one or more carbon rings. The general formula for saturated hydrocarbons is CnH2n ring with 1. [2]
4. Aromatic hydrocarbons, also known as the arena, are hydrocarbons that have at least one aromatic ring.
Gaseous hydrocarbon (eg methane and propane), liquids (eg hexane and benzene), waxes or solids with a low boiling point (eg paraffin wax and naphthalene) or polymers (eg, polyethylene, polypropylene and polystyrene).

Because of its molecular structure is different, then the empirical formula of the hydrocarbon was also different: the amount of hydrocarbon bound to alkenes and alkynes definitely less because carbon atoms bonded duplicate.
The ability of hydrocarbons to bond with itself called katenasi, and cause hydrocarbons can form compounds that are more complex, such as cyclohexane or benzene arena. This ability is obtained due to the characteristics of the bonds between carbon atoms are non-polar.
In accordance with the valence bond theory, the carbon atom must satisfy the rule "4-hydrogen" which states the maximum number of atoms that can be bonded to the carbon, because carbon has four valence electrons. Judging from the valence electrons, the carbon has four electrons that can form covalent bonds or dative bonds.
Hydrocarbons are hydrophobic and are included in the lipid.
Some hydrocarbons are available in abundance in the solar system. Lakes containing liquid methane and ethane have been found on Titan, the largest natural satellite of Saturn, as stated by the Cassini-Huygens mission. [5]
