The diagram shows the repeat unit of a polymer. Which row correctly identifies the monomer and type of polymerisation involved in making this polymer?

This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.

Amonomer: [Monomer A, showing CH2=CH(C2H5)], type of polymerisation: addition

Bmonomer: [Monomer B, showing CH2=CH(C2H5)], type of polymerisation: condensation

Cmonomer: [Monomer C, showing a non-alkene structure], type of polymerisation: addition

Dmonomer: [Monomer D, showing a non-alkene structure], type of polymerisation: condensation

✓ Correct answer

A: monomer: [Monomer A, showing CH2=CH(C2H5)], type of polymerisation: addition
