Organic Chemistry

Carbon's ability to form four bonds, long chains and rings gives millions of compounds, and a handful of naming rules, functional groups and reaction types let you predict how each one behaves.

  1. 1Hydrocarbons: Naming and Isomers
  2. 2Functional Groups and Their Properties
  3. 3Stereoisomers and Chirality
  4. 4Organic Reactions
  5. 5Polymers and Organic Compounds in Society
  6. 6Organic Compounds in Everyday Life: Risks, Benefits and Choices
Unit 2 · 5 lessons · ~20% of course

Structure and Properties of Matter

How the arrangement of electrons inside atoms decides how atoms bond, what shape molecules take, and why a substance is a gas, a brittle crystal, a hard gem or a shiny metal.

  1. 1From Rutherford to the Quantum Atom
  2. 2Electron Configurations
  3. 3Molecular Shape and Polarity
  4. 4Intermolecular Forces and Types of Solids
  5. 5Seeing Structure: Spectroscopy and Instrumental Analysis
Unit 3 · 5 lessons · ~20% of course

Energy Changes and Rates of Reaction

How much energy a reaction releases or absorbs, how to measure and predict that energy with calorimetry, Hess's law and bond energies, and why some reactions are explosive while others take years.

  1. 1Enthalpy Changes and Calorimetry
  2. 2Hess's Law and Enthalpies of Formation
  3. 3Physical, Chemical and Nuclear Energy: Fuels Compared
  4. 4Rates of Reaction and Collision Theory
  5. 5Potential Energy Diagrams and Mechanisms

Chemical Systems and Equilibrium

Many reactions never run to completion: they settle into a dynamic balance that can be described with an equilibrium constant, pushed around by changing conditions, and used to calculate pH, solubility and the shape of a titration curve.

  1. 1Dynamic Equilibrium and the Equilibrium Constant
  2. 2Le Chatelier's Principle and the Reaction Quotient
  3. 3Acid-Base Equilibria
  4. 4Solubility Equilibria, Buffers and Titration
  5. 5Equilibrium at Work: Industry, Body and Environment
  6. 6Measuring K in the Lab

Electrochemistry

Redox reactions move electrons from one substance to another. Keep track of those electrons and you can balance any redox equation, build a battery, predict whether a reaction will happen, and explain electroplating and rust.

  1. 1Oxidation Numbers and Redox Reactions
  2. 2Balancing Redox with Half-Reactions
  3. 3Galvanic Cells and Cell Potential
  4. 4Electrolytic Cells, Corrosion and Batteries
