Question

Is gasoline a mixture of volatile alkanes and aromatic hydrocarbons? Why?

Answer 1

Gasoline is a petroleum-derived product comprising a mixture of liquid aliphatic and aromatic hydrocarbons, ranging between $C_4$ and $C_{12}$ carbon atoms with the boiling range of 30–225°C.

It is predominantly a mixture of paraffins, naphthenes, aromatics, and olefins.

Gasoline, also spelled gasolene, also called gas or petrol, mixture of volatile, flammable liquid hydrocarbons derived from petroleum and used as fuel for internal-combustion engines. It is also used as a solvent for oils and fats.

Originally a by-product of the petroleum industry (kerosene being the principal product), gasoline became the preferred automobile fuel because of its high energy of combustion and capacity to mix readily with air in a carburetor.
