A chemist has two unlabelled samples of polymer. One sample is an addition polymer and the other sample is a condensation polymer. The chemist knows the structure of the repeating unit and the structures of the monomers for each sample.
Describe how the chemist could use this information to decide which sample is the condensation polymer.
Suggest why a molecule that contains one carbon to carbon double bond and no other functional group cannot be used to make a condensation polymer.
