WebAlkanes are not very reactive and have little biological activity; all alkanes are colorless and odorless non-polar compounds. The relative weak London dispersion forces of alkanes result in gaseous substances for short carbon chains, volatile liquids with densities around 0.7 g/mL for moderate carbon chains, and solids for long carbon chains. WebAlkanes are saturated hydrocarbons (substances composed solely of carbon and hydrogen, with only single bonds); alkanes have a general formula C H 2 + 2.
