🎯 Exam Focus
Frequently Examined
Simple molecules feature in most chemistry papers. The most common question patterns:
- Explain the low melting point of a named simple molecular substance — always reference "weak intermolecular forces" not "weak covalent bonds" (2 marks)
- Explain why it doesn't conduct electricity — "no ions and no free electrons" (2 marks)
- Compare melting points of two simple molecular substances of different sizes (2 marks)
- Identify the type of structure from given properties (low MP, doesn't conduct) (1 mark)
A question may give you unfamiliar molecules — apply the same principles. If it's simple molecular: low MP, doesn't conduct, often liquid or gas at room temperature.
