AP Chemistry is a college-level introductory chemistry course that explores matter from the atomic level up through complex chemical systems. The course builds from the structure of atoms and the bonds that connect them, through how molecules interact and react, to the rates and energetics of reactions, and finally to the balance points and proton-transfer reactions that govern acids, bases, and electrochemical systems.
This page covers all 9 units — Atomic Structure & Properties, Molecular & Ionic Compound Structure & Properties, Intermolecular Forces & Properties, Chemical Reactions, Kinetics, Thermodynamics, Equilibrium, Acids & Bases, and Applications of Thermodynamics.
Every page on this site is aligned to the College Board's official AP Chemistry Course and Exam Description and completely free. Use what works for your study style — flashcards for active recall, the cheat sheet for a one-page overview, or practice questions to test yourself before the exam.
