Chemistry — Grade 12
American Curriculum · Ages 17-18
Twelfth grade Chemistry is AP Chemistry taken as a senior, or an elective such as Organic Chemistry or a college-credit dual-enrolment course. Students taking it are almost always heading for medicine, engineering, pharmacy or a physical science major, and the grade carries weight in admissions.
Where the course is organic chemistry, the work shifts from calculation to pattern recognition: functional groups, nomenclature, and reaction mechanisms drawn with curly arrows. Students who try to memorise reactions individually struggle; the ones who learn to reason from electron movement handle unfamiliar reactions on sight, which is exactly what examiners test.
Key topics covered
- Structure & Bonding ReviewHybridisation, resonance, formal charge and molecular shape.
- Functional Groups & NomenclatureRecognising and systematically naming organic compounds.
- Reaction MechanismsCurly arrow notation, nucleophiles, electrophiles and intermediates.
- Substitution & EliminationComparing pathways and predicting the dominant product.
- SpectroscopyInterpreting IR, mass and NMR spectra to determine structure.
- Advanced Equilibrium & ThermodynamicsSolubility products, coupled equilibria and free energy.
- Exam & College PreparationAP free response, laboratory write-ups and dual-enrolment assessment.
