8 weeks · About 7 hours per week

Week 1

Organic Chemistry: Hydrocarbons, Functional Groups and Reaction Pathways

  • Map every hydrocarbon and functional-group interconversion in the syllabus onto a single reaction-pathway flowchart drawn from memory, then check it against notes and mark gaps in red.

  • Write out mechanisms for electrophilic addition to alkenes, free-radical substitution in alkanes, and nucleophilic substitution (SN1 vs SN2) side by side, labelling curly arrows, intermediates and rate-determining steps.

  • Predict and explain the major product for 15 unfamiliar reaction prompts (Markovnikov/anti-Markovnikov, rearrangements, stereochemistry), writing a one-sentence justification for each.

  • Build a table distinguishing tests and reagents (KMnO4, Br2 in CCl4, Tollens', Fehling's, Brady's, iodoform) with the exact observation expected for each functional group.

Your checkpoint

A single A3-size handwritten reaction-pathway map plus a 15-question self-test scored out of 15, with every wrong answer annotated with the corrected mechanism.

Week 2

Organic Chemistry: Hydrocarbons, Functional Groups and Reaction Pathways & Analytical and Instrumental Techniques (including spectroscopy and separation methods)

  • Convert the week-1 pathway map into a set of 10 synthesis problems (multi-step, 3-5 steps each) and solve them without notes, then verify each route.

  • Explain how IR, mass spectrometry and NMR each distinguish a named pair of isomers, writing the specific absorption, m/z fragment or splitting pattern that differs.

  • Interpret 8 supplied spectra descriptions (peak positions and splitting given in text) and assign a structure to each with reasoning.

  • Describe the principles and practical steps of solvent extraction, recrystallisation, distillation and chromatography, stating one criterion for choosing each.

Your checkpoint

A spectroscopy-and-synthesis workbook: 10 solved synthesis routes and 8 structure assignments, each with a written justification of at least three sentences.

Week 3

Chemical Equilibrium, Acids, Bases, Buffers and Solubility

  • Derive and apply Ka, Kb, Kw, pH, pOH and buffer (Henderson-Hasselbalch) expressions to calculate pH for strong/weak acids, bases and buffer systems, including dilution and partial neutralisation cases.

  • Solve 12 calculation problems spanning buffer preparation, pH after adding strong acid/base, and indicator selection, showing full working with units and significant figures.

  • State and apply Le Chatelier's principle and write Kc/Kp expressions, then calculate equilibrium composition from initial amounts for at least 4 systems.

  • Apply Ksp to predict precipitation, calculate molar solubility in pure water and in a common-ion solution, and explain the common-ion effect quantitatively.

Your checkpoint

A worked problem set of 12 equilibrium/acid-base/solubility calculations, timed at 90 minutes, with a self-marked score and a list of the three error types made.

Week 4

Thermochemistry, Energetics and Chemical Thermodynamics

  • Draw and interpret Born-Haber cycles and enthalpy-level diagrams for at least 5 compounds, labelling every term including lattice enthalpy, electron affinity and hydration enthalpy.

  • Calculate ΔH using Hess's law, standard enthalpy of formation and mean bond enthalpy data, and explain why bond-enthalpy routes give different answers from formation routes.

  • Apply entropy and Gibbs free energy (ΔG = ΔH − TΔS) to predict spontaneity, calculate the temperature at which a reaction becomes feasible, and explain the effect of temperature on ΔG.

  • Explain calorimetry procedure (q = mcΔT) and identify three sources of systematic error in an enthalpy-of-combustion experiment with a correction for each.

Your checkpoint

Five fully labelled Born-Haber/energy-cycle diagrams plus 10 energetics calculations, all checked against a mark scheme, with a one-page summary of sign conventions and common traps.

Week 5

Atomic Structure, Electronic Configuration and the Periodic Table & Chemical Bonding and Intermolecular Forces

  • Write electron configurations (including ions and exceptions such as Cr and Cu) using s, p, d notation and box notation, and relate them to periodic trends in atomic radius, ionisation energy and electronegativity.

  • Explain anomalies in ionisation energy trends and first-row transition-metal properties (variable oxidation state, complex formation, colour, catalysis) with electronic reasons.

  • Draw dot-and-cross and shape diagrams for at least 12 species, deducing hybridisation and bond angles from VSEPR, and identify lone-pair distortions.

  • Classify intermolecular forces in named substances and rank boiling points with justification, distinguishing hydrogen bonding, permanent dipole–dipole and induced dipole forces.

Your checkpoint

A one-page annotated periodic-trend summary plus a 12-species VSEPR and bonding table, both reproduced from memory and then corrected.

Week 6

Electrochemistry, Redox and Transition-Metal Chemistry & Reaction Kinetics and Reaction Mechanisms

  • Assign oxidation states and balance complex redox equations in acidic and alkaline media using half-equations and electrons, checking 10 examples.

  • Construct and use standard electrode potentials to predict cell feasibility, calculate E°cell and relate E° to ΔG (ΔG = −nFE°), and explain the limitations of predictions.

  • Describe transition-metal complex geometry, ligand substitution, and colour explained by d-orbital splitting, and apply the chemistry of at least three transition metals to qualitative analysis.

  • Apply rate laws, order determination from initial-rate and graphical data, and the Arrhenius equation; write rate equations for SN1/SN2 and explain how mechanism follows from kinetics.

  • Explain how concentration, temperature, pressure, surface area and catalysts affect rate in collision-theory terms, and sketch and interpret energy profile diagrams with and without catalyst.

Your checkpoint

A two-part timed paper: 10 balanced redox equations with E°cell and ΔG calculations, plus a 6-question kinetics set including two order determinations from tabulated data, marked and error-logged.

Week 7

Stoichiometry, Formulae and the Mole Concept & Gases, Kinetic Theory and States of Matter

  • Convert between mass, moles, concentration, gas volume and particles for 15 mixed problems including limiting reagent, percentage yield, empirical formula and titration calculations.

  • Apply the ideal gas equation and Dalton's law of partial pressures to gas-mixture and stoichiometry problems, and explain deviations from ideality in terms of intermolecular forces and molecular volume.

  • Describe the kinetic theory assumptions and use them to explain Boyle's, Charles's and Avogadro's laws qualitatively and quantitatively.

  • Explain the shapes of heating/cooling curves and phase diagrams in terms of energy changes and intermolecular forces, including latent heat calculations.

  • Design and write up a full procedure for one titration (including indicator choice and standard solution preparation) and one enthalpy or rate experiment, listing apparatus, safety precautions and disposal.

  • Identify and correct unsafe or invalid procedures in 6 short written scenarios, naming the specific hazard, control measure and the effect of the error on the result.

  • Process a supplied data set (readings, burette values, repeated titres) to calculate a mean with correct significant figures, identify outliers, and calculate percentage error and uncertainty.

  • Complete two full-length mixed mock papers under exam conditions, then classify every lost mark by domain to build a final revision list.
