Edexcel IAL Chemistry A2 19.10 physical properties of polyamides and poly(ethenol)
Use the intermolecular force explicitly: polyamides have strong hydrogen bonds between chains, while poly(ethenol) can hydrogen-bond to water through OH groups.
How this is tested
- Explain higher polyamide melting points using hydrogen bonds between chains.
- Link poly(ethenol) solubility to hydrogen bonding between OH groups and water.
- Suggest practical advantages of soluble laundry bags or glycerol-modified polymers.
