Alkenes have at least one double bond and alkynes have at least one triple bond. The most common alkyne is ethyne, better known as acetylene. The generic formula for alkanes is C n H 2n+2, where n is the number identified by the prefix. Alkenes have the formula C n H 2n and alkynes use the formula C n H 2n-2.

General formula for Alkane is CnH(2n+2) ; n is integer, n= 1, 2, 3…. For alkene it is CnH(2n) ; n = 2, 3, 4… For alkyne it is CnH(2n-2) ; n = 2,3,4… Since, alkene and alkynes refers to double bonded carbons & tripple bonded carbons respectively, there must be at least 2 carbon atoms. Hence, the value of n starts from 2.

Chemical properties. Alkynes are characteristically more unsaturated than alkenes. Thus they add two equivalents of bromine whereas an alkene adds only one equivalent in the reaction. Other reactions are listed below. In some reactions, alkynes are less reactive than alkenes.For example, in a molecule with an -ene and an -yne group, addition occurs preferentially at the -ene.

In organic chemistry, an alkane, or paraffin (a historical 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. Alkanes have the general chemical formula C n H 2n+2.

Decalin is an alkane that has two rings fused together, so it is classified as a cyclic alkanes, with a general chemical formula of CnH2(n+1-g). Each edge of the chemical structure corresponds to ...

Alkynes: Molecular and Structural Formulas. ... the alkyne of molecular formula C 4 H 6 has two isomers, Although alkynes possess restricted rotation due to the triple bond, they do not have stereoisomers like the alkenes because the bonding in a carbon‐carbon triple bond is sp hybridized.

Hydrocarbons with the same formula, including alkanes, can have different structures. For example, two alkanes have the formula C 4 H 10: They are called n-butane and 2-methylpropane (or isobutane), and have the following Lewis structures:. The compounds n-butane and 2-methylpropane are structural isomers (the term constitutional isomers is also commonly used).

Alkane molecules have only single bonds between carbon atoms.. Alkene molecules have a double bond ().. Alkyne molecules have a triple bond ().. The following examples show the 4 carbon alkane, alkene, and alkyne. Notice that the alkene only has one double bond and the alkyne only has one triple bond.

The alkanes comprise a series of compounds that are composed of carbon and hydrogen atoms with single covalent bonds. This group of compounds comprises a homologous series with a general molecular formula of C n H 2 n+2 , where equals any integer. The simplest alkane, methane, has one carbon atom ...

Organic chemistry is the study of carbon compounds, so the study of organic chemistry is important because all living things are based on carbon compounds. Carbon is unique in that it can form up to four bonds in a compound, so they can easily bond with other carbon atoms, forming long chains or rings. In addition, the type of bonding in organic compounds is almost always covalent.
