Chemistry (9701)
AS and A Level Chemistry notes following the Cambridge International 9701 syllabus, across physical, inorganic and organic chemistry and analysis.
Margin's Chemistry notes follow the Cambridge International AS & A Level Chemistry syllabus (9701), in two courses: AS Chemistry and A Level Chemistry.
Courses and papers#
| Course | Label | Covers | Assessed in |
|---|---|---|---|
| AS Chemistry | AS | The AS topics and practical skills | Paper 1 (multiple choice), Paper 2 (AS structured questions), Paper 3 (advanced practical skills) |
| A Level Chemistry | A2 | The A Level topics and planning skills | Paper 4 (A Level structured questions), Paper 5 (planning, analysis and evaluation) |
What the courses cover#
The syllabus is organised into four strands, each of which runs through both courses:
| Strand | AS | A Level |
|---|---|---|
| Physical chemistry | Atomic structure, amount of substance, bonding, states of matter, energetics, redox, equilibria, rates | Lattice energy and entropy, electrochemistry, further equilibria including buffers and , further kinetics |
| Inorganic chemistry | Periodicity, Group 2, Group 17, nitrogen and sulfur | Further Group 2 chemistry, transition elements |
| Organic chemistry | Formulae and isomerism, hydrocarbons, halogenoalkanes, alcohols, carbonyls, carboxylic acids, nitrogen compounds, polymers, synthesis | Arenes, further functional groups, polymerisation, organic synthesis |
| Analysis | Infrared spectroscopy, mass spectrometry | NMR spectroscopy, chromatography |
The Chemistry courses are being written now, so their units fill in over time.
What to expect in a note#
- Equations written with proper chemical notation, including state symbols and equilibrium arrows:
- Reaction mechanisms described step by step, naming each curly-arrow movement
- Comparison tables for closely related ideas, such as and
- Practical skills blocks for titrations, enthalpy experiments, rates and tests for ions
- Exam tip blocks on the precise wording examiners expect in definitions and explanations
