Chemistry

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 Review — Hybridisation, resonance, formal charge and molecular shape.
• Functional Groups & Nomenclature — Recognising and systematically naming organic compounds.
• Reaction Mechanisms — Curly arrow notation, nucleophiles, electrophiles and intermediates.
• Substitution & Elimination — Comparing pathways and predicting the dominant product.
• Spectroscopy — Interpreting IR, mass and NMR spectra to determine structure.
• Advanced Equilibrium & Thermodynamics — Solubility products, coupled equilibria and free energy.
• Exam & College Preparation — AP free response, laboratory write-ups and dual-enrolment assessment.
