🎯 Exam Focus
Frequently Examined
Giant covalent structures are a high-frequency topic. The diamond/graphite comparison is a classic question:
- Compare diamond and graphite — structure, properties, and explain the differences (4-6 marks)
- Explain why giant covalent structures have high melting points — reference covalent bonds being broken (2 marks)
- Explain why graphite conducts electricity — delocalised electrons moving along layers (2 marks)
- Identify the structure from given properties — very high MP + conducts = graphite (1 mark)
- Higher tier: Fullerenes/graphene — structure and uses in medicine, electronics (2-3 marks)
