Practise ethyl-ethanoate formula questions by drawing displayed ester linkages and placing each carbon chain clearly and correctly.

How this is tested

  • Draw ethyl ethanoate with a fully displayed ester linkage and all bonds shown.
  • Complete displayed ester formulae by placing the -COO- group between the correct chains.

Question 4(c)(iv)

[Maximum number: 2]

This question is about the reactions of ethanol and ethanoic acid.

A student prepares the ester, ethyl ethanoate, by reacting ethanol with ethanoic acid.

This is the student's method.
- mix equal amounts of ethanol and ethanoic acid in a boiling tube
- add a few drops of concentrated sulfuric acid
- place the boiling tube in a hot water bath for several minutes

Draw the displayed formula of ethyl ethanoate.
