Esters (GCSE)

Structure Esters have the functional group –COO– Production Ethyl ethanoate (CH3COOCH2CH3) is the ester produced from ethanol and ethanoic acid in the presence of concentrated sulfuric acid catalyst. Properties They are volatile compounds with distinctive smells and are used as flavourings and perfumes. Candidates will not be expected to give the names of esters other than ethyl ethanoate, but should be able to recognise a compound as an

Carboxylic acids (GCSE)

Ethanoic acid is a member of the carboxylic acids, which have the functional group –COOH. Candidates 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. Properties of carboxylic acids: ■ dissolve in water to produce acidic solutions ■ react with

Alcohols

Alcohols contain the functional group –OH Methanol, ethanol and propanol are the first three members of a homologous series of alcohols. These have the general formula CnH2n+1OH Properties and uses Methanol, ethanol and propanol: ■ dissolve in water to form a neutral solution ■ react with sodium to produce hydrogen ■ burn in air [equations needed] ■ are used as fuels and
