There are 75 isomers of decane, all of which are flammable liquids. n-Decane, (straight-chain decane), has a melting point of -30 °C or -22 °F, a boiling point of 174 °C or 345 °F, and a specific gravity of 0.73. Decane is one of the components of gasoline (petrol). Decane, like other alkanes, is nonpolar and therefore will not dissolve in polar liquids such as water.
