Alkanes have the general chemical formula C n H 2n+2. The alkanes range in complexity from the simplest case of methane ( CH 4 ), where n = 1 (sometimes called the parent molecule), to arbitrarily large and complex molecules, like pentacontane ( C 50 H 102 ) or 6-ethyl-2-methyl-5-(1-methylethyl) octane, an isomer of tetradecane ( C 14 H 30 ).
Alkanes are organic compounds that consist of single-bonded carbon and hydrogen atoms. The formula for Alkanes is CnH2n+2, subdivided into three groups – chain alkanes, cycloalkanes, and the branched alkanes.
Alkanes are the most basic compounds in Organic Chemistry. However, they are also very important as they form the backbones of many other complex compounds. In this article, you will learn about the structure of alkane, its nomenclature, and some of its reactions.
23 sty 2023 · Alkanes have the general formula CnH2n+2 C n H 2 n + 2 and can be subdivided into the following three groups: the linear straight-chain alkanes, branched alkanes, and cycloalkanes. Alkanes are also saturated hydrocarbons.
The principle of homology allows us to write a general formula for alkanes: C n H 2 n + 2. Using this formula, we can write a molecular formula for any alkane with a given number of carbon atoms. For example, an alkane with eight carbon atoms has the molecular formula C 8 H (2 × 8) + 2 = C 8 H 18.
The alkanes are a homologous series of hydrocarbons with the general formula C n H 2n+2. The models show the first four unbranched members of this series. You can also see the structural and displayed formulae for these alkanes.
For alkanes, the general formula is. C n H 2n+2. So, for example, methane with one carbon atom has (2 x 1) + 2 carbon atoms so the formula is CH 4. Octane with 8 carbon atoms has (2 x 8) + 2 carbon atoms so the formula is C 8 H 18. Notice that as you go from one alkane to the next, the formula increases by CH 2. The alkanes. The alkanes are ...
