A textile laboratory analyses two polymer fibres, P and Q. Each fibre is either an addition polymer or a condensation polymer.
The table compares the atoms in the monomer molecule or molecules needed for one repeating unit with the atoms in that repeating unit.
| Polymer fibre | Atoms in the monomer molecule or molecules | Atoms in one repeating unit |
|---|---|---|
| P | 4 carbon, 8 hydrogen | 4 carbon, 8 hydrogen |
| Q | 9 carbon, 18 hydrogen, 6 oxygen | 9 carbon, 14 hydrogen, 4 oxygen |
Describe how the results identify the condensation polymer.
