SCH4U — Grade 12 Chemistry (Ontario)
SCH4U is Ontario's Grade 12 university-preparation chemistry course, following The Ontario Curriculum, Grades 11–12: Science (2008). This page is your map: each of the five units below links straight to the ChemistNate notes that cover it. If you took SCH3U first, you already know the foundations — stoichiometry, bonding, and gas laws — that this course builds on.
Unit 1: Structure and Properties of Matter
Atomic theory, quantum numbers, periodic trends, chemical bonding, molecular shapes, and intermolecular forces.
Unit 2: Energy Changes and Rates of Reaction
Enthalpy, Hess's law, entropy, free energy, and how fast reactions run.
Unit 3: Chemical Systems and Equilibrium
Dynamic equilibrium, Le Châtelier's principle, acids and bases, buffers, and solubility.
Unit 4: Organic Chemistry
Nomenclature, stereochemistry, reaction mechanisms, and the major functional-group families — including polymers.
Unit 5: Electrochemistry
Oxidation numbers, redox half-reactions, galvanic and electrolytic cells, and standard cell potentials.
