Alkane - Wikipedia
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 - Formula, Definition, Structure, Properties, List of Alkanes ...
The formula for Alkanes is CnH2n+2, subdivided into three groups – chain alkanes, cycloalkanes, and the branched alkanes. Alkanes are a series of compounds that contain carbon and hydrogen atoms with single covalent bonds. These are known as saturated hydrocarbons.
12.2: Structures and Names of Alkanes - Chemistry LibreTexts
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 …

2023年1月23日 · Alkanes are organic compounds that consist entirely of single-bonded carbon and hydrogen atoms and lack any other functional groups. Alkanes have the general formula \(C_nH_{2n+2}\) and can be subdivided into the following three groups: the linear straight-chain alkanes, branched alkanes, and cycloalkanes. Alkanes are also saturated ...

2022年4月18日 · Alkanes are the simplest organic compounds made up of carbon and hydrogen only. They have the general formula C n H 2n+2. They are also known as saturated hydrocarbons since their carbon skeleton is entirely saturated with hydrogens. Alkanes consist of strong C-C and C-H covalent bonds, so they are relatively chemically inert.
