From the electron to the equilibrium.

Cambridge AS & A Level Chemistry 9701 is thirty-seven syllabus topics in two halves. AS Level Chemistry is topics 1 to 22 - the physical chemistry of atomic structure, atoms molecules and stoichiometry, chemical bonding, states of matter, chemical energetics, electrochemistry, equilibria and reaction kinetics; the inorganic chemistry of the Periodic Table, Group 2, Group 17, and nitrogen and sulfur; the whole of AS organic chemistry from hydrocarbons to polymerisation and organic synthesis; and analytical techniques. A Level Chemistry is those twenty-two topics plus topics 23 to 37, which take energetics, electrochemistry, equilibria and reaction kinetics further, add the chemistry of the transition elements, and extend the organic chemistry to the A Level hydrocarbons including arenes, halogen compounds, hydroxy compounds, carboxylic acids and derivatives, nitrogen compounds, polymerisation, organic synthesis and analytical techniques.

Every topic sits in one of four strands - Physical chemistry, Inorganic chemistry, Organic chemistry and Analysis - and every revision page on this site sits in one of them, in Cambridge's own order. AS Level candidates study the first half and sit three papers; A Level candidates study all of it and sit five.

• AO1 40% — Knowledge and understanding
• AO2 40% — Handling, applying and evaluating information
• AO3 20% — Experimental skills and investigations

The full topic list, with every topic linked to its revision page, is on the AS & A Level Chemistry syllabus page. Work through the areas below in order, or jump straight to what you need tonight.
