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.
Stay tuned! Bonus features for this video are under development...
Our Chemistry Lessons playlist gives you practical help for the topics that chemistry students often struggle with. Each video has multiple example problems worked out in full. Topics covered include: Balancing Chemical Equations, the MOLE, Gas Laws, Molar Mass, and more.
