CAIE IGCSE Chemistry 11.2.4 Displayed formulae of the unbranched

Practise naming and drawing ester structures made from short unbranched alcohols and carboxylic acids.

Exam points

name esters by linking the alcohol alkyl group to the acid-derived alkanoate name
draw displayed ester formulae with the correct -COO- linkage and carbon chain lengths
choose the ester formed from a given alcohol and carboxylic acid pair

[Maximum number: 2]

Propane, propene, propan-1-ol and propanoic acid are members of different homologous series. Molecules of these substances contain three carbon atoms.

Propanoic acid forms an ester when it reacts with ethanol in the presence of a catalyst.
