Hydrocarbons are chemical compounds made up of hydrogen and carbon. The simplest of these is methane and natural gas. Oil is a hydrocarbon fuel because it is made up of various compounds rather like methane, but it is liquid rather than gas. Alkanes are referred to as saturated hydrocarbons which act as the basis for petroleum fuels and are found in linear and branched forms.
