A homologous series of organic compounds have the same general formula, and show similar chemical properties and physical property trends.

The functional group is the atom or group of atoms responsible for the way a compound reacts.

Calorimetry is an experiment that can be used to measure the energy released from a fuel.

Viscosity is how easily a liquid flows. The higher the viscosity, the less easily a liquid flows.

Chemical tests involving alkanes, alkenes and alcohols

Chemistry

Alkenes

Alcohols

Combustion of alcohols: planning

Combustion of alcohols: practical

Carboxylic acids and esters

Addition polymerisation

Polymer properties and problems

Condensation polymerisation

Natural polymers

In the Chemistry of Carbon unit, pupils learned about the structure and bonding of carbon, and its ability to form various compounds.

This unit covers identifying functional groups, naming and drawing structural formulae, and predicting reactions of alkanes, alkenes, alcohols, and carboxylic acids. It explains addition and condensation polymerisation and discusses natural polymers like DNA, sugars, and amino acids.
