Carboxylic acids are a homologous series of           compounds that contain the -COOH functional group.

Weak acids partially dissociate to form Hᐩ ions in solution.

A carbonate is a compound containing the CO₃²ᐨ ion. An example is calcium carbonate CaCO₃.

Esters are a homologous series of compounds that contain the -COO- functional group.

Ethyl ethanoate is an ester produced from the alcohol ethanol and the carboxylic acid ethanoic acid.

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.
