Curated OER
Chapter 14 Review, Section 2: Acids and Bases
Lewis acids and bases, Brønsted-Lowry acids and bases, ionization, and more are covered by this chemistry handout. It serves as a review of a specific textbook section, but will also serve as a nice review for any general chemistry...

Working out the Shapes of Molecules
In this molecular geometry worksheet, students are given the directions and 4 examples as to how to predict the geometry of molecules. They determine if the molecules are pyramidal or trigonal bipyramidal.

Washinton University: Vsepr
This site from the Department of Chemistry at Washington University is a nice site in that it gives you a graphical look at the arrangement of electron pairs. The plug-in CHIME will let you see the 3-D molecules, but it is good even if...

State University of New York: Determining Electron Pair Geometry
The electron-pair geometry of a molecule or ion depends on the number of structurally significant electron pairs in the central atom. Here students are asked to count the number of lone electron pairs and bonded atoms on the central...
