Key terms
finite resource
A natural resource that is limited in quantity and will eventually be depleted
crude oil
A naturally occurring, viscous liquid found in underground rock formations, composed mainly of hydrocarbons
Crude oil
A finite resource found in rocks, consisting mainly of the remains of ancient biomass, primarily plankton, buried in mud.
Biomass
Organic material derived from living or recently living organisms, which in the case of crude oil, mainly consists of plankton.
Crude oil
A finite resource found in rocks, consisting of a mixture of a very large number of compounds.
Hydrocarbon
A compound consisting entirely of hydrogen and carbon atoms, commonly found in crude oil.
Hydrocarbon
A compound consisting entirely of hydrogen and carbon atoms, commonly found in crude oil.
Crude Oil
A finite resource found in rocks, composed of a mixture of many different hydrocarbons.
alkanes
Hydrocarbons that consist only of single bonds and follow the general formula CnH2n+2.

Alkane
A saturated hydrocarbon with the general formula CnH2n+2.
Homologous series
A group of organic compounds with the same functional group and similar chemical properties, differing by a CH2 unit.
Alkane
A saturated hydrocarbon with the general formula CnH2n+2, consisting of carbon and hydrogen atoms.
Methane
The simplest alkane with the molecular formula CH4, consisting of one carbon atom and four hydrogen atoms.
Alkane
A saturated hydrocarbon with the general formula CnH2n+2, consisting only of single bonds between carbon atoms.
Molecular Formula

Alkane
A saturated hydrocarbon with the general formula CnH2n+2, consisting only of single C–C and C–H bonds.
Molecular Formula
A concise representation of the number and type of atoms in a molecule, written as a chemical formula such as C4H10 for butane.
Alkane
A saturated hydrocarbon with the general formula CnH2n+2, consisting only of single bonds.
Molecular modelling kits
Tools used to create three-dimensional models of molecules, helping to visualize the structure of alkane molecules.
Fractional Distillation
A process used to separate a mixture into its component fractions based on different boiling points.
Hydrocarbon Fraction
A specific group of hydrocarbons that have a similar number of carbon atoms, separated during fractional distillation.
Fraction
A fraction is a portion of crude oil that contains molecules with a similar number of carbon atoms.
Hydrocarbon
A hydrocarbon is a compound consisting entirely of hydrogen and carbon atoms, commonly found in crude oil.
Fraction
A distinct component of a mixture, containing molecules with a similar number of carbon atoms, separated during fractional distillation.
Feedstock
Raw materials used in the petrochemical industry to produce fuels and other chemical products.
Petrol
A liquid fuel derived from the middle fractions of crude oil, used primarily in spark‑ignition internal combustion engines.
Diesel oil
A heavier liquid fuel obtained from the lower fractions of crude oil, used in compression‑ignition engines.
petrochemical
