Noncovalent interactions refers to electrostatic forces that do not involve shared pairs of electrons and includes ionic interactions, hydrophobic interactions, van der Waals interactions, and hydrogen bonding. These types of interactions play a particularly important role in biochemistry and the study of protein folding.

Floating Squares
// Tuesday, June 3, 2014 • Deanna Cullen
I was looking for a new demonstration to initiate a discussion about polarity and related properties to use as part of an exam review. I found a video at ChemEd X (this is part of a ChemEd X subscription). It is entitled “Floating Squares – Hexane and Water” (see note below). I have placed both solutions together before, but I had not added the squares. The demonstration fulfilled my needs. I could have used the original video and muted it if I had not had hexane to demonstrate with.
