One page per syllabus topic, in Cambridge's own numbering. These build directly on the AS topics, so work through those first.
Chemical energetics
This A Level topic covers the energies that hold ionic lattices together and the direction in which change happens. You will define lattice energy, enthalpy of atomisatio...

Revise this topicElectrochemistry
Electrochemistry at A Level links the charge passed through a cell to the amount of substance made, and the potential difference between two half-cells to whether a react...

Revise this topicEquilibria
Aqueous equilibria go beyond Kc: acid strength is measured by Ka and pKa, the ionisation of water fixes the pH scale through Kw, the solubility of a sparingly soluble sal...

Revise this topicReaction kinetics
Rate equations turn a reaction into numbers: rate = k[A]m[B]n, with orders found by experiment from initial rates, concentration-time curves or half-lives. You then work ...

Revise this topicGroup 2
Group 2 at A Level is about explaining, not just describing. This topic explains the thermal stability of the carbonates and nitrates from the polarising power of the cat...

Revise this topicChemistry of transition elements
The first-row transition elements, titanium to copper, are d-block elements whose ions have partly filled 3d orbitals. That single feature explains their variable oxidati...

Revise this topicAn introduction to A Level organic chemistry
At A Level, organic chemistry is organised by functional group and by mechanism. This topic covers the extra classes of compound you must know and name, the characteristi...

Revise this topicHydrocarbons
Arene chemistry is the chemistry of the delocalised ring. This topic covers the evidence for delocalisation in benzene, why the ring substitutes rather than adds, the mec...

Revise this topicHalogen compounds
Halogenoarenes such as chlorobenzene are made by substituting a halogen into an arene ring, using a halogen carrier as the catalyst. This topic covers the electrophilic s...

Revise this topicHydroxy compounds: acyl chlorides, phenol and phenolic compounds
Phenol is a weak acid whose activated ring is nitrated and brominated under mild conditions, while an alcohol is esterified in minutes by an acyl chloride. This covers es...

Revise this topicCarboxylic acids and derivatives (A Level)
Acyl chlorides are the most reactive carboxylic acid derivatives: they are made from carboxylic acids with PCl3, PCl5 or SOCl2 and are attacked by nucleophiles in an addi...

Revise this topicNitrogen compounds
Amines are nitrogen-containing bases, made from halogenoalkanes, nitriles and amides, and their base strength depends on whether the nitrogen lone pair is free or delocal...

Revise this topicPolymerisation
Condensation polymerisation joins monomers that each carry two functional groups, forming polyesters and polyamides and losing water or hydrogen chloride at every link. T...

Revise this topicAdvanced organic synthesis
Advanced organic synthesis is the skill of getting from one named compound to another on purpose. You identify every functional group in a molecule that holds several, pr...

Revise this topicAnalytical techniques (A Level)
Chromatography, carbon-13 NMR and proton NMR separate, identify and quantify the compounds in a mixture. This topic covers the two phases and Rf values, retention times a...
