💡 Exam Tips for Polymers
🎯 Common Question Types:
- Draw the polymer from a given monomer structure (2 marks)
- Identify the monomer from a repeat unit (1-2 marks)
- Explain the low melting point of a polymer (2 marks)
- Name the type of polymerisation (1 mark)
- Explain why polymers are electrical insulators (2 marks)
📝 Key Command Words:
- Draw: Change double to single bond, add brackets, add n, show bonds at each end of repeat unit
- Identify: The monomer is the repeat unit with C=C restored (double bond added back)
- Explain: Reference weak intermolecular forces between chains for low MP
- Name: "Addition polymerisation" for monomer with C=C double bond
⚠️ Common Mistakes to Avoid:
- Forgetting to draw the bonds coming out of the brackets in polymer repeat units
- Saying "the double bonds hold the chains together" — they're covalent bonds within the chain
- Saying "ionic bonds" hold polymer chains together — they're intermolecular forces
- Confusing the monomer with the repeat unit in diagrams (the monomer has a C=C double bond)
