  1. 1Carbon Bonding and Molecular ShapeConnect carbon’s bonding patterns to the shapes, strengths, and reactive regions of organic molecules.
  2. 2Drawing Organic MoleculesTranslate between structural formulas and use three-dimensional conventions to interpret molecular shape.
  3. 3Classifying Organic CompoundsOrganise organic molecules by their carbon frameworks, functional groups, and homologous relationships.
  4. 4Naming HydrocarbonsBuild systematic names by choosing, numbering, and describing the correct carbon framework.
  5. 5Naming Compounds with Functional Groups and Benzene RingsUse functional-group priority and ring substitution to move confidently between names and structures.
  6. 6Isomerism: One Formula, Different CompoundsDistinguish different connectivities and spatial arrangements without confusing them with different drawings of one molecule.
  7. 7Bond Breaking and Reactive SpeciesFollow electrons through bond cleavage and identify the species that begin organic reactions.
  8. 8Inductive and Resonance EffectsExplain how attached groups and delocalised electrons shape charge distribution and stability.
  9. 9Electromeric Effect, Hyperconjugation, and Reaction PatternsConnect reagent-induced electron shifts and sigma-electron delocalisation to stability and broad reaction outcomes.
  10. 10Purifying Compounds by Physical PropertiesChoose a purification method by connecting solubility, volatility, and boiling behaviour to the mixture.
  11. 11Chromatography and SeparationRead chromatograms by following how components divide between stationary and mobile phases.
  12. 12Identifying Elements in Organic CompoundsConnect elemental-test observations with the chemical conversions that make them possible.
  13. 13Measuring Carbon, Hydrogen, and NitrogenDerive elemental percentages from combustion products, gas volumes, and acid–base measurements.
  14. 14Measuring Halogens, Sulphur, Phosphorus, and OxygenUse precipitate masses and conservation of atoms to complete an elemental composition analysis.
  15. 15Chapter Summary and PracticeConnect molecular structure, reactivity, purification, and elemental evidence in a complete organic-chemistry workflow.
