Hydrocarbons are very ubiquitous in nature. Crude petroleum is primarily a hydrocarbon mixture which is divided into various fractions that can be marketed. Gasoline is the fraction that consists primarily of hexane (C6), heptane (C7), and octane (C8) and the carbon skeletons can be in a straight chain, branched, or cyclic. Other fractions, used for other purposes, consist of mixtures of higher or lower molecular weight hydrocarbons, e.g., natural gas, kerosene, motor oil. The hydrocarbon molecules can also be either saturated or unsaturated.
