CAIE A Level Chemistry 33.2.1 Preparing Esters

Practise forming ethyl ethanoate and phenyl benzoate by reacting alcohols or phenols with acyl chlorides, identifying ester products and the accompanying hydrogen chloride.

Exam points

react ethanoyl chloride with ethanol to form ethyl ethanoate while retaining the CH3CO– acyl group
react benzoyl chloride with phenol or phenoxide to form phenyl benzoate
distinguish O-acylation forming an ester from N-acylation forming an amide in multifunctional molecules
