How to teach intermolecular forces at 14–16

Molecules are one of the key particles secondary students learn about in chemistry. At 14–16, they need to be able to visualise what molecules are and how they are different from giant structures. They also need to understand intermolecular forces. Progressing from London dispersion forces, to permanent dipoles, to discussing hydrogen bonding can be challenging for students. Use the detailed teaching advice and explanations in this article to help them understand this topic and avoid misconceptions.
