Dipole Dipole Forces

This video takes a look at dipole-dipole forces, one of the main categories of intermolecular forces (IMFs), including: where they come from, their impacts on boiling points, and how the magnitude of the dipole moment influences their strength. We begin with a review of the electrostatic interaction and the necessity of molecular polarity for dipole forces. Then we explore some empirical examples with period 3 hydrogen compounds to see how the magnitude of the dipole moment impacts boiling points. Finally, we close with some practical comparisons of fluorocarbon compounds and nitromethane to see the impact of pure dipole-dipole forces.
