Exam questions on Acyl chlorides, esters and polyesters

1. Ethanoyl chloride, CH₃COCl, is a colourless liquid that fumes in moist air. It is used in the laboratory to make a range of other organic compounds.
   Write a balanced equation for the reaction of ethanoyl chloride with concentrated ammonia and name the organic product.2 marks
2. Ethyl ethanoate is an ester used as a solvent. A student hydrolyses it by heating under reflux, first with dilute hydrochloric acid and then, in a second experiment, with aqueous sodium hydroxide.
   Write the equation for the alkaline hydrolysis of ethyl ethanoate and state what must be added to the product mixture to obtain ethanoic acid.2 marks
3. Propanoyl chloride, CH₃CH₂COCl, is added separately to ethanol, to methylamine, CH₃NH₂, and to concentrated ammonia.
   Name the organic product formed in each of the three reactions.3 marks
