Carboxylic acids and esters
I can describe the structure of the first four carboxylic acids, and recognise and describe reactions where carboxylic acids are involved.

Lesson details
Key learning points
- Carboxylic acids have a -COOH functional group.
- Carboxylic acids are weak acids.
- When ethanol is oxidised, ethanoic acid is formed.
- Carboxylic acids react with carbonates to produce a metal salt, carbon dioxide and water.
- Carboxylic acid can react with alcohol to produce esters (such as ethyl ethanoate).
Keywords
Carboxylic acids - Carboxylic acids are a homologous series of compounds that contain the -COOH functional group.
Weak acids - Weak acids partially dissociate to form Hᐩ ions in solution.
Carbonate - A carbonate is a compound containing the CO₃²ᐨ ion. An example is calcium carbonate CaCO₃.
Esters - Esters are a homologous series of compounds that contain the -COO- functional group.
Ethyl ethanoate - Ethyl ethanoate is an ester produced from the alcohol ethanol and the carboxylic acid ethanoic acid.
Common misconception
Confusing the concentration and strength of acids.
Clearly define a strong and weak acid.
