What are Intermolecular Forces? || Chemical Bonds || Chemistry

Chemistry students often confuse Intermolecular Forces and Intramolecular Forces. What are Intermolecular Forces? These are the electrostatic attractions that draw different chemical species together. There are two main kinds of intermolecular forces: dipole interactions and dispersion forces. In this video, we'll do a survey of the various kinds of intermolecular bonds, collectively known as "van der Waals Interactions."

"INTER-" refers to the forces between two different chemical species. "INTRA-" refers to the forces within a SINGLE chemical molecule or compound that holds it together. We have separate videos about intramolecular bonds, like ionic bonds and covalent bonds.

You can click on the links below to jump to sections in the lesson:
0:00 Overview of Intermolecular Forces/ van der Waals
0:35 Types of Dipole Interactions
0:41 Ion-Dipole Forces - Ions attracted to a polar molecule
1:24 Ion-induced Dipole Interactions
2:25 Dipole-Dipole Forces - Two polar molecules attracted to each other
3:06 Hydrogen Bonds - Special case of Dipole Dipole interaction
4:32 Dispersion Forces
6:39 Intermolecular Forces vs Intramolecular Forces

About our instructor:
Kimberly Hatch Harrison received degrees in Biology and English Literature from Caltech before working in pharmaceuticals research, developing drugs for autoimmune disorders. She then continued her studies in Molecular Biology (focusing on Immunology and Neurobiology) at Princeton University, where she began teaching as a graduate student. Her success in teaching convinced her to leave the glamorous world of biology research and turn to teaching full-time. Kimberly taught AP Biology and Chemistry at an exclusive prep school for eight years. She is now the head writer and producer of Socratica Studios.
