Benzene vs. Gasoline: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on January 21, 2024
Benzene is a volatile, aromatic hydrocarbon often used as an industrial solvent, while gasoline is a complex fuel mixture used in internal combustion engines.

Key Differences

Benzene, a simple aromatic hydrocarbon with a sweet odor, is primarily used in chemical synthesis. Gasoline, on the other hand, is a complex blend of hydrocarbons used as a fuel in vehicles. Both are derived from crude oil but have different applications and properties.
In terms of chemical structure, benzene consists of a six-carbon ring with alternating double bonds, making it a stable yet reactive compound. Gasoline is a variable mixture of different hydrocarbons, including alkanes, cycloalkanes, and in some cases, small amounts of benzene. Each has distinct chemical and physical properties relevant to their use.
Benzene is known for its use in the manufacture of plastics, resins, and synthetic fibers, as well as a solvent in many industrial processes. Gasoline's primary use is as a fuel in internal combustion engines, powering vehicles. Both are essential in their respective sectors.
Regarding health and environmental impacts, benzene is a known carcinogen and requires careful handling and exposure control. Gasoline, while less toxic than benzene, poses environmental concerns, particularly in terms of air pollution and spill risks. Both have significant health and environmental considerations.
In terms of volatility, benzene has a high evaporation rate and is highly flammable, necessitating strict safety measures during handling. Gasoline also has high volatility, which is essential for its use in fueling internal combustion engines, but also makes it a fire hazard.

Benzene and Gasoline Definitions


Benzene is a colorless, sweet-smelling chemical compound.
The laboratory used benzene in organic synthesis experiments.


It's derived from the refining of crude oil.
Gasoline is a key product of petroleum refineries.


It's used as a precursor in the production of plastics.
Benzene forms the base for many plastic materials.


Gasoline vapors are highly flammable.
Care must be taken to avoid igniting gasoline vapors.


Benzene is known for its carcinogenic properties.
Safety protocols are essential when handling benzene due to its toxicity.


Gasoline is a liquid fuel used primarily in vehicles.
The car runs efficiently on unleaded gasoline.


It is a natural constituent of crude oil.
Benzene is refined from crude oil in chemical plants.


It's a mixture of various hydrocarbons.
Gasoline's composition varies between brands and types.


Benzene has a high rate of evaporation.
Benzene quickly evaporates at room temperature.


Gasoline powers internal combustion engines.
Most automobiles use gasoline to drive their engines.


A colorless, flammable, toxic, liquid aromatic hydrocarbon, C6H6, derived from petroleum and used in or to manufacture a wide variety of chemical products, including DDT, detergents, insecticides, and motor fuels. Also called benzol.


A volatile mixture of flammable liquid hydrocarbons derived chiefly from crude petroleum and used principally as a fuel for internal-combustion engines.


(organic compound) An aromatic hydrocarbon of formula C6H6 whose structure consists of a ring of alternate single and double bonds.


A flammable liquid consisting of a mixture of refined petroleum hydrocarbons, mainly used as a motor fuel; petrol.


Sometimes used in place of the phenyl group.


(countable) Any specific kind of gasoline.
The refinery produces a wide range of gasolines.


A volatile, very inflammable liquid, C6H6, contained in the naphtha produced by the destructive distillation of coal, from which it is separated by fractional distillation. The name is sometimes applied also to the impure commercial product or benzole, and also, but rarely, to a similar mixed product of petroleum.


Marijuana, especially very potent or high quality.


A colorless liquid hydrocarbon; highly inflammable; carcinogenic; the simplest of the aromatic compounds


(slang) An alcoholic beverage made of vodka and energy drink.


Made from or using gasoline.


A highly volatile mixture of fluid hydrocarbons, obtained mostly from petroleum, as also by the distillation of bituminous coal. It is used as a fuel for most automobiles and for many other vehicles with internal combustion engines. The gasoline of commerce is typically blended with additives to improve its performance in internal combustion engines. Gasoline was also used in the early 1900's in making air gas, and in giving illuminating power to water gas. See Carburetor.


A volatile flammable mixture of hydrocarbons (hexane and heptane and octane etc.) derived from petroleum; used mainly as a fuel in internal-combustion engines
