- Alcohols contain the functional group –OH.
Methanol, ethanol, propanol and butanol are the first four members of a homologous series of alcohols.
Alcohols can be represented in the following forms: CH3CH2OH
Students should be able to:
- describe what happens when any of the first four alcohols react with sodium, burn in air, are added to water, react with an oxidising agent
- recall the main uses of these alcohols.
- Aqueous solutions of ethanol are produced when sugar solutions are fermented using yeast.
- Students should know the conditions used for fermentation of sugar using yeast.
- Students should be able to recognise alcohols from their names or from given formulae.
- Students do not need to know the names of individual alcohols other than methanol, ethanol, propanol and butanol.
- Students are not expected to write balanced chemical equations for the reactions of alcohols other than for combustion reactions.
AT 2 Safe use of appropriate heating devices and techniques including use of a Bunsen burner and a water bath or electric heater (links to A-level AT b)
AT 5 Making and recording of appropriate observations during chemical reactions including changes in temperature and the measurement of rates of reaction by a variety of methods such as production of gas and colour change (links to A-level AT a and l).
AT 6 Safe use and careful handling of gases, liquids and solids, including careful mixing of reagents under controlled conditions, using appropriate apparatus to explore chemical changes and/or products (links to A-level AT a and k).
