REVISION NOTES GUIDE SUMMARY: What do you need to know
for the examinations? What do you need to able to do in the exams? In AQA GCSE Science
A examinations HT means for higher tier students only.
Sorry, but I don't have much time to answer questions, but if you see any
apparent errors or wish to comment, please
email me. All my notes, learning
objectives, comments for exam revision are based on the official AQA GCSE Science A Key Stage 4
Throughout this unit you will be
expected to write word equations for reactions specified.
Higher tier (HT)
candidates will also be expected to write and balance symbol
equations for reactions specified throughout the unit.
AQA GCSE Science CHEMISTRY Unit C3.6 Alcohols, carboxylic acids and esters
Appreciate that alcohols and carboxylic acids
are important organic chemicals that have many uses.
Know that alcohols react with carboxylic
acids to produce esters.
You should be able to use
your skills, knowledge and understanding to:
represent the structures of
alcohols in the following forms:
represent the structures of carboxylic acids in the following
evaluate the social and economic
advantages and disadvantages of the uses of alcohols, carboxylic acids and
AQA GCSE Science CHEMISTRY Unit C3.6.1 Alcohols
a) Know alcohols contain the functional group –OH.
ethanol and propanol are the first three members
of a homologous series of alcohols.
You should be able to recognise alcohols from their names
or formulae, but do not need to know the names of individual alcohols, other
than methanol, ethanol and propanol.
b) Know that methanol, ethanol and propanol:
dissolve in water to form a neutral solution
react with sodium to produce hydrogen
burn in air
are used as a fuels and solvents
the main alcohol in alcoholic drinks.
c) Know that ethanol can be oxidised to ethanoic acid, either by
chemical oxidising agents or by microbial action.
AQA GCSE Science CHEMISTRY Unit C3.6.2 Carboxylic acids
a) Know that ethanoic acid is a member of the carboxylic acids,
which have the functional group –COOH.
should be able to recognise carboxylic acids from their names or formulae,
but do not need to know the names of individual carboxylic acids, other than
methanoic acid, ethanoic acid and propanoic acid.
b) Know that carboxylic acids:
dissolve in water to produce acidic solutions
react with carbonates to produce carbon dioxide
react with alcohols in the presence of an acid
catalyst to produce esters
HT only: do not ionise completely when dissolved in
water and so are weak acids
HT only: aqueous solutions of weak acids have a higher
pH value than aqueous solutions of strong
acids with the same concentration.
AQA GCSE Science CHEMISTRY Unit
a) Ethyl ethanoate is the ester produced from ethanol
and ethanoic acid.
You will not be expected to give the names of
esters other than ethyl ethanoate, but should be able to
recognise a compound as an ester from its name or its
