CAIE A-Level Chemistry 33.3.2 Reactions of Acyl Chlorides

Practise predicting room-temperature products of acyl chlorides with water, alcohols, phenols, ammonia and amines.

Exam points

hydrolyse an acyl chloride with water to the carboxylic acid and HCl at room temperature
form an ester with an alcohol or phenol by replacing Cl with the oxygen-containing group
form an amide with ammonia or a primary/secondary amine, retaining nitrogen substituents and producing HCl
