The chemical formula for gasoline varies depending on where it is from. C8H18 is a good average. There may aslo be sulfur, or other trace elements in it.

Gasoline, or petrol, is made of a mixture of hydrocarbons, which are molecules composed of carbon and hydrogen atoms.Typically, in standard gasoline, the hydrocarbons consist of carbons chains are 5-10 carbon atoms long.

The exact mixture of which types of hydrocarbons depends entirely on the specific sample of gasoline (what type of oil it was made from, which company refined it, what additives were added, etc.)

See the Web Links below for more information about hydrocarbons.

Chemical composition: C8H18

There is no fixed formula for gasoline. Because of the "octane rating" used in motor fuel rating, many users think gasoline contains all octane (trimethylpentane, C8H18), but it actually consists of a variety of volatile hydrocarbons from butane to benzene to toluene, and others.

All gasolines and diesels are formulated to meet performance criteria, not composition criteria - like wine tasting and blending, the same results can be reached with a number of different components.

The bulk of gasoline consists of hydrocarbons called alkanes, with the number of carbon atoms per molecule between 5 and 12. Thus C5H12 pentane, C6H14 hexane, C7H16 heptane, C8H18 octane, C9H20 nonane, C10H22 decane, C11H24 undecane, C12H26 dodecane.

basically, water, carbon dioxide, maybe some nitrogen oxides depending in the combustion temperature, carbon monoxide (particularly with small engines (lawn mowers, chain saws, etc) and older cars).

Gasoline is a mixture and does not have any consistent chemical composition. Gasoline's predominant constituents are alkanes with from 6 to 12 carbon atoms per molecule.

Since most cars are designed to run on gasoline, ethanol is often blended with gasoline in ratios that allow normal cars to run. Most cars will accept E10 and many will accept E30. E85 requires vehicles be designed or specially outfitted to handle fuel with such ethanol concentration.

What are chemical and physical properties of gasoline?

Gasoline has various chemical properties (particularly, it burns very well) and its combustion products have other chemical properties (they don't burn as well) but it would not be correct to say that gasoline in any sense BECOMES a chemical property. Chemicals have properties, they don't become properties.


Is combustion of gasoline a physical change?

Combustion of gasoline changes the chemical properties of the matter, and is thus a chemical change, not a physical one.


Is separation of water and gasoline a physical change?

No, it is a physical change. The water and gasoline retain their chemical and physical properties.
