Synthetic resins can be made by polymerisation of a variety of monomers including prop-2-en-1-ol, CH₂=CHCH₂OH. Which structure represents the repeat unit in poly(prop-2-en-1-ol)?

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.

A[Structure of −CH₂−CH₂−CH₂−O− polymer repeat unit]

B[Structure of −CH₂−CH(CH₂OH)− polymer repeat unit]

C[Structure of −CH=C(CH₂OH)− polymer repeat unit]

D[Structure of −CH₂−CH₂−CH(OH)− polymer repeat unit]

✓ Correct answer

B: [Structure of −CH₂−CH(CH₂OH)− polymer repeat unit]
