Answer
On heating in the presence of air or dioxygen, alkanes are completely oxidized to carbon dioxide and water with the evolution of a large amount of heat. This is known as combustion reaction of alkanes.
General representative equation for combustion is: $C _n H _{2 n +2}+\left(\frac{3 n+1}{2}\right) O _2 \longrightarrow nCO _2+(n+1) H _2 O +$ Heat
