  1. 1Hydrocarbon Families and Alkane StructuresSee how carbon skeletons distinguish hydrocarbon families and generate alkane isomers.
  2. 2Naming Branched AlkanesTranslate accurately between branched carbon skeletons, substituent names, and systematic names.
  3. 3Making Alkanes and Explaining Their Physical PropertiesChoose alkane preparation routes and connect molecular size and shape to observable properties.
  4. 4Alkane Reactions and Radical ChainsExplain radical substitution and use reaction conditions to distinguish alkane transformations.
  5. 5Single-Bond Rotation and the Alkene Double BondConnect ethane conformations and alkene geometry to the orbitals holding their bonds.
  6. 6Naming, Isomerism, and Preparation of AlkenesName and compare alkenes, then choose preparations that create their double bonds and geometry.
  7. 7Alkene Addition and Product DirectionPredict addition products by following electron movement and intermediate stability.
  8. 8Alkene Oxidation, Ozonolysis, and PolymersDistinguish reactions that add oxygen, reveal a double-bond position, or build long molecular chains.
  9. 9Alkyne Structure, Names, and PreparationConnect the linear triple bond to alkyne isomerism and methods for making ethyne.
  10. 10Alkyne Acidity, Addition, and PolymerisationExplain terminal-alkyne acidity and track the products formed when two pi bonds react.
  11. 11Benzene Structure and AromaticityUse structural evidence and delocalisation to explain aromatic stability and recognise aromatic systems.
  12. 12Preparing Benzene and Understanding Its ReactionsRelate benzene preparations and reaction mechanisms to the loss and restoration of aromaticity.
  13. 13Predicting Substitution on Aromatic RingsUse substituent effects to predict both the ease and position of further aromatic substitution.
  14. 14Chapter Summary and PracticeConnect bonding, isomerism, reaction mechanisms, and structural evidence across every hydrocarbon family.
