Alkane. In organic chemistry, an alkane, or paraffin (a historical trivial name that also has other meanings), is an acyclic saturated hydrocarbon. In other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single. [1] Alkanes have the general chemical formula CnH2n+2.
List of straight-chain alkanes. The following is a list of straight-chain alkanes, the total number of isomers of each (including branched chains), and their common names, sorted by number of carbon atoms. [1][2] Number of C atoms. Number of isomers [3][4] Number of isomers including stereoisomers [3][5] Molecular Formula. Name of straight chain.
The shorter of the two chains becomes the first part of the name with the -ane suffix changed to -oxy, and the longer alkane chain becomes the suffix of the name of the ether. Thus, CH 3 OCH 3 is methoxymethane, and CH 3 OCH 2 CH 3 is methoxyethane (not ethoxymethane). If the oxygen is not attached to the end of the main alkane chain, then the ...
The naming of polycyclic alkanes such as bicyclic alkanes and spiro alkanes is more complex, with the base name indicating the number of carbons in the ring system, a prefix indicating the number of rings ( "bicyclo-" or "spiro-"), and a numeric prefix before that indicating the number of carbons in each part of each ring, exclusive of ...
Pentane is an organic compound with the formula C 5 H 12 —that is, an alkane with five carbon atoms. The term may refer to any of three structural isomers, or to a mixture of them: in the IUPAC nomenclature, however, pentane means exclusively the n-pentane isomer, in which case pentanes refers to a mixture of them; the other two are called isopentane (methylbutane) and neopentane ...
Category:Alkanes. Wikimedia Commons has media related to Alkanes. The main article for this category is Alkane. An alkane is a saturated hydrocarbon. See Alkane . Alkanes as substituents are called alkyl groups.
An open-chain compound having no side groups is called a straight-chain compound (also spelled as straight chain compound). [2][3] Many of the simple molecules of organic chemistry, such as the alkanes and alkenes, have both linear and ring isomers, that is, both acyclic and cyclic. For those with 4 or more carbons, the linear forms can have ...
Hydrocarbon. Ball-and-stick model of the methane molecule, CH 4. Methane is part of a homologous series known as the alkanes, which contain single bonds only. In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. [1]: 620 Hydrocarbons are examples of group 14 hydrides.
