Space-filling models of the pentane molecule

Pentanes are solvents in many ordinary products. Because of their low boiling points, low cost, and relative safety, pentanes are used as a working medium in geothermal power stations and organic Rankine cycles. It is also used in some blended refrigerants. Pentanes are relatively inexpensive and are the most volatile liquid alkanes at room temperature, so they are often used in the laboratory as solvents that can be conveniently and rapidly evaporated. However, because of their nonpolarity and lack of functionality, they dissolve only nonpolar and alkyl-rich compounds. Pentanes are miscible with most common nonpolar solvents such as chlorocarbons, aromatics, and ethers. They are often used in liquid chromatography. Like other alkanes, pentanes are largely unreactive at standard room temperature and conditions - however, with sufficient activation energy, they readily oxidize to form carbon dioxide and water.
