- Crude oil, hydrocarbons and alkanesCrude oil is a finite resource found in rocks.
- Fractional distillation and petrochemicalsThe many hydrocarbons in crude oil are separated into fractions by fractional distillation.
- Properties of hydrocarbonsSome properties of hydrocarbons depend on the size of their molecules: boiling point, viscosity and flammability.
- Cracking and alkenesLarge hydrocarbon molecules can be broken down into smaller, more useful molecules.
- Structure and formulae of alkenesAlkenes are hydrocarbons that contain a double bond between two carbon atoms, written C=C.
- Reactions of alkenesThe C=C functional group decides how alkenes react.
- AlcoholsAlcohols contain the functional group -OH.
- Carboxylic acidsCarboxylic acids contain the functional group -COOH.
- Addition polymerisationAlkenes can be used to make polymers such as poly(ethene) and poly(propene).
- Condensation polymerisation (HT only)Condensation polymerisation involves monomers that each have two functional groups.
- Amino acids (HT only)Amino acids are molecules that have two different functional groups: an amino group (-NH2) and a carboxylic acid group (-COOH).
- DNA (deoxyribonucleic acid) and other naturally occurring polymersDNA (deoxyribonucleic acid) is a large molecule that is essential for life.
