polarity

Lewis Dot, VSEPR Shape, Polarity and Intermolecular Forces Activity Sheet

Determination of Lewis Dot structures and visualization of the shapes of molecules using VSEPR theory is an example of an abstract concept that students often find difficult to learn. I have found it useful to have a single worksheet/packet that my students can add to as we cover Lewis dot structures, resonance, VSEPR shapes, polarity, and intermolecular forces.

Floating Squares

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 . It is entitled “” (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.
