A 3D model of ethyne , the simplest alkyne. In organic chemistry, an alkyne is an unsaturated hydrocarbon containing at least one carbon—carbon triple bond. [1] The simplest acyclic alkynes with only one triple bond and no other functional groups form a homologous series with the general chemical formula C n H 2n−2.
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

The first eight members of the series (in terms of number of carbon atoms) are named as follows: methane CH 4 – one carbon and 4 hydrogen ethane C 2 H 6 – two carbon and 6 hydrogen propane C 3 H 8 – three carbon and 8 hydrogen butane C 4 H 10 – four carbon and 10 hydrogen pentane C 5 H 12 – five carbon and 12 hydrogen hexane C 6 H 14 ...
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
[10] [11] Often this energy is used directly as heat such as in home heaters, which use either petroleum or natural gas. The hydrocarbon is burnt and the heat is used to heat water, which is then circulated. A similar principle is used to create electrical energy in power plants. Both saturated and unsaturated hydrocarbons undergo this process.
Name General Description Acetic acid: an organic acid; is one of the simplest carboxylic acids: Acetone: an organic compound; simplest example of the ketones: Acetylene: a hydrocarbon and the simplest alkyne; widely used as a fuel and chemical building block
First, five atoms comprise the longest straight chain of carbon centers. The parent five-carbon compound is named pentane (highlighted blue). The methyl "substituent" or "group" is highlighted red. According to the usual rules of nomenclature, alkyl groups are included in the name of the molecule before the root, as in methylpentane. This name ...
