chemistry hydrocarbon

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)

Hydrocarbons Compounds



Hydrocarbons are the most simple carbon compounds. From the name, hydrocarbon compounds are compounds composed of only carbon and hydrogen atoms karbon.Berdasarkan atomic arrangement of carbon atoms in the molecule, carbon compounds are divided into two major categories, namely aliphatic compounds and cyclic compounds.

   1.  Aliphatic hydrocarbons

Aliphatic hydrocarbons are carbon compounds chain opens its C and C it allows branched chain. Based on the amount of the bond, aliphatic hydrocarbons, aliphatic compounds are divided into saturated and unsaturated.

a. The compound is a saturated aliphatic C chain aliphatic compounds it contains only single bonds only. This group is called alkanes.


b. Unsaturated aliphatic compounds are aliphatic compounds, varying chain C double bond or triple. If you have duplicate named alkenes and alkynes have triple called.
 

 2.Cyclic hydrocarbons

Cyclic hydrocarbon compound is a compound of carbon chain C and its circular hoop may also bind the side chain. This group divided into alicyclic and aromatic compounds.

  a. alicyclic compounds are carbon compounds that make up the chain aliphatic alicyclic compounds tertutup


b. Aromatic compounds are compounds composed of 6 carbon atoms that form a chain C benzene.
