The reaction of an alkane with oxygen to produce carbon dioxide and water is known as combustion.
Alkanes are a family of hydrocarbons that are composed of carbon-carbon single bonds in their molecules.
The general molecular formula of alkanes is CₙH₂ₙ₊₂.
The alkanes are known as saturated hydrocarbons due to the absence of any double or triple carbon-carbon bonds in their molecules.
The first member of the alkane family of hydrocarbons is methane with the molecular formula CH₄.
The two main reactions of the alkanes are combustion and substitution reactions.
In combustion reactions, alkenes react with oxygen to produce carbon dioxide and water as well as large amounts of heat and light energy.
The combustion of methane is shown below:
CH₄ (g) + O₂ (g) ---> CO₂ (g) + H₂O (g)
Hence, alkanes are important fuels used in households and industries.
