Question 10

This question is about simple test-tube reactions to identify organic liquids.

1.

Silver nitrate solution can be used to distinguish between propanoyl chloride and 1-chloropropane.

Give the observations you would expect when a few drops of silver nitrate solution are added to separate samples of propanoyl chloride and 1-chloropropane at room temperature.

  • Observation with propanoyl chloride:
  • Observation with 1-chloropropane:

2.

Three unlabelled bottles are known to contain either pentan-1-ol, pentanal, or pentan-2-one.

A sample of each liquid is warmed with Fehling's solution.

  • Identify the liquid that reacts with Fehling's solution and give the expected observation.
  • Suggest a further simple test-tube reaction that can be used to distinguish between the remaining two liquids.
  • Give the expected observation with the liquid that reacts to this further test.
