Understanding Alkanes: Properties, Classification, and Applications

alkanes

simple hydrocarbons CnH(2n+2)suffix –> aneprefix –> ane –> yl n —yl – this indicates that it is normal/ straight chain ex. undecane

Alkanes are a group of organic compounds that contain only single covalent bonds between carbon and hydrogen atoms. They are also known as paraffins and are the simplest type of hydrocarbons. The general formula for alkanes is CnH2n+2, where n is the number of carbon atoms in the molecule.

Alkanes are classified based on the number of carbon atoms in the molecule, and each class has a unique prefix to indicate the number of carbon atoms. For example, methane (CH4) has one carbon atom and is a member of the alkane family. The prefix for one carbon atom is “meth-.” Therefore, the next members of the alkane family after methane are ethane (C2H6), propane (C3H8), butane (C4H10), and so on.

Alkanes are typically unreactive due to the strength of the single carbon-carbon bonds. However, they can undergo combustion reactions with oxygen to produce carbon dioxide and water:

CnH2n+2 + (3n+1)/2 O2 → nCO2 + (n+1)H2O

Alkanes are also used as fuels and as raw materials for the production of other compounds, such as plastics and solvents. They can be obtained from crude oil through fractional distillation, which separates the different hydrocarbons based on their boiling points.
