WEEK 3 STUDY GUIDE
Message to Lumist AP Learners
Hi AP Campers! Welcome to week three of AP Chemistry. This week’s unit
is Intermolecular Forces and Properties, which covers 18-22% of the final exam.
We will begin by discussing intermolecular forces and how they determine the
properties of solids, liquids, and gases. Next, we will learn about ideal gases and their
characteristics according to the Kinetic Molecular Theory. This week will also cover the
ideal gas law equation and deviations from this law. Some other topics from this unit
are solutions and solubility rules. Lastly, this unit will examine the wave-particle duality
of light and Einstein’s Nobel prize-winning discovery of the Photoelectric effect. This
finding led to our understanding of light as not just a wave but also a particle.
Similar to last week, this guide includes key insights to help you avoid common
misunderstandings and remember key concepts. The end of this guide has a problem
set with questions you can expect on exams. The problem set has a bonus question for
students who want extra practice and a bit of a challenge.
Good luck!
Chapter 1 Overview: Topics & Concepts
3.1 Intermolecular Forces (IMF)
London Dispersion: electrons constantly moving create net + and – areas that
interact with oppositely charged areas in neighbouring molecules.
Dipole-Dipole: polar compounds with dipoles interact with oppositely charged
dipoles in other molecules.
Hydrogen bonding: arise from the highly polar bond between H and F, O, or N. This
results in δ+ H interacting with an electronegative atom of another molecule (F, O,
or N). ex. hydrogen bonding is seen in DNA and water.
Ion-dipole: an ion interacting with a polar compound. Cations interact with the
negation end of a dipole. Anions interact with the positive end of the dipole. ex. HCl
in water.
Ionic Bonding: the electrostatic attraction between ionic molecules.
Skillset: Identify the type of IMFs a molecule experiences by its structure
