Find the ester link first, then reconstruct the diol and acid fragments or draw continuation bonds so the repeat unit has the correct atoms at each end.
How this is tested
- Choose repeat units formed from a named diol and dicarboxylic acid pair.
- Draw two repeat units with ester linkages and continuation bonds shown.
- Deduce the two monomers or single hydroxy-acid monomer from the repeat unit.
