Decane is an alkane hydrocarbon with the chemical formula C10H22 with 75 structural isomers.[3] These isomers are flammable liquids. Decane is a component of gasoline (petrol). Like other alkanes, it is nonpolar and does not dissolve in polar liquids, such as water. It has a surface tension of 0.0238 N·m−1.[4]

Reactions

Decane undergoes combustion reactions in a similar fashion to other alkanes. In the presence of excess oxygen, decane burns to form water and carbon dioxide.

2C10H22 + 31O2 → 20CO2 + 22H2O

When not enough oxygen is present for complete combustion, decane burns to form water and carbon monoxide.

2C10H22 + 21O2 → 20CO + 22H2O
