Question

Among addition and condensation polymers, which does have the same empirical formula as of its monomer?

Answer 1

1. Addition polymers have the same empirical formula as their monomers.
2. This is because no small molecule is eliminated during polymerisation.
3. Example: Polyethene is formed from ethene (CH₂ = CH₂) without any loss of atoms.
4. In contrast, condensation polymers eliminate small molecules like water or HCl, so their empirical formula changes.
