- The chemical composition depends on its source, but it usually consists of about 10 different hydrocarbons, each containing 10 to 16 carbon atoms per molecule. The main constituents are saturated straight-chain and branched-chain paraffins, as well as ring-shaped cycloparaffins (also known as naphthenes).

When formulated as a fuel for engines, gasoline is chemically composed of organic compounds derived from the fractional distillation of petroleum and later chemically enhanced with gasoline additives. It is a high-volume profitable product produced in crude oil refineries. [1]
Gasoline is a complex mixture of molecules with a boiling range of 40–200°C (104–392°F). To produce various grades, there is a blending of many refinery components, each of which promotes specific fuel qualities such as desired octane rating, volatility, and minimization of engine deposits.
describe the general nature of petroleum deposits, and recognize why petroleum is such an important source of organic compounds. explain, in general terms, the processes involved in the refining of petroleum. define the octane number of a fuel, and relate octane number to chemical structure.
Petroleum refining begins by fractional distillation of crude oil into three principal cuts according to boiling point (bp): straight-run gasoline (bp 30–200 °C), kerosene (bp 175–300 °C), and heating oil, or diesel fuel (bp 275–400 °C).
Jun 24, 2022 · Gasoline structure is a hydrocarbon compound, so it is an organic molecule. The general formula of gasoline is CnH2n+2. So, gasoline is an alkane molecule. Petrol is one example of gasoline. Gasoline structure is as similar to alkane structure.
Some of the hydrocarbons in gasoline are small and contain just four carbon atoms, while others are much larger and have up to twelve carbons. Some hydrocarbons form straight lines, while others have a branched structure; some have only single bonds, while others have double bonds; and still others contain rings.
Gasoline is a complex chemical mixture of refined petroleum produced from crude oil. Gasoline is primarily composed of carbon and hydrogen atoms, typically ranging from four-carbon compounds (C4; butane) to twelve-carbon compounds (C12; dodecane).
