Chunking is the strategy of breaking large, complex topics into smaller, manageable parts. Instead of revising all of Organic Chemistry in one go, break it into chunks like:
Functional groups
Reaction types
Mechanisms
Nomenclature
Spectroscopy
This approach reduces overload and makes revision more structured. After studying each chunk, test your understanding using active recall — and then link the chunks back together to see the bigger picture. It’s a smart way to master detail without getting overwhelmed.
Example:
Energetics/Thermochemistry:
Energetics Chunks:
Enthalpy change definitions – formation, combustion, neutralisation
Hess’s Law – applying enthalpy cycles
Bond Enthalpies – calculating ∆H using average bond energies
Exothermic vs Endothermic – interpreting energy profiles
Calorimetry – using q = mc∆T in calculations
✅ How to use: After mastering each chunk, combine into past paper Qs that ask for analysis + calculation (e.g. determine ∆H from data + evaluate method).
