Learn the 9 conceptsteach yourself first, then practise each
Covalent bonds — formation and properties of covalent compounds2–3 marks
Show electron sharing (single, double, triple bonds) and explain the low melting points and poor conductivity.
Tetravalency and catenation of carbon1–2 marks
Explain why carbon forms so many compounds.
Saturated and Unsaturated Carbon Compounds1–5 marks
Tell alkanes (only single bonds) from alkenes and alkynes (double / triple bonds) and write their structures.
Chains, Branches and Rings1–5 marks
Draw straight-chain, branched and ring skeletons, and the structural isomers of a formula such as C₄H₁₀.
Homologous series (general formula, e.g. CₙH₂ₙ₊₂)2–3 marks Visual
Predict the next member's formula and properties trend.

Identify and name the group; predict typical reactions.
Chemical Properties of Carbon Compounds1–5 marks
