CAIE IGCSE Chemistry 11.8.9 Differences Between Addition and Questions

Work through real CAIE IGCSE Chemistry questions to distinguish polymerisation types, released small molecules and functional-group requirements.

Exam points

distinguish addition polymerisation, where the polymer is the only product, from condensation polymerisation
state that condensation polymerisation releases a small molecule such as water while joining monomers with functional groups
identify polyesters, polyamides and natural polymers as condensation polymers and alkenes as addition-polymer monomers
explain why condensation monomers need reactive functional groups and why a molecule without C=C cannot undergo addition polymerisation

[Maximum number: 1]

The structure of a synthetic polymer is shown.
