Presents exercises where students can check their understanding of the Valence-Shell Electron-Pair Repulsion Model by predicting what a molecular shape will be. Requires Java.

An advanced explanation of the valence shell electron pair repulsion (VSEPR) theory describes specific molecular models involving digonal, trigonal, tetrahedral, and octahedral coordination, as well as central atoms with five bonds....

Why does the shape of a molecule matter? Learn about how the shape of the molecule not only determines the molecule's properties but also whether it reacts or not. This tutorial reviews of VSEPR and molecular geometry.

[Free Registration/Login may be required to access all resource tools.] The following online tutorial explains the basis of VSEPR theory. It helps students predict the shapes of molecules and polyatomic ions using VSEPR theory and it...

In this interactive activity from ChemThink, students will learn about covalent molecules and how the VSEPR theory predicts the shapes of covalently-bonded molecules.

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...

Explore molecule shapes by building molecules in 3D. How does molecule shape change with different numbers of bonds and electron pairs? Find out by adding single, double or triple bonds and lone pairs to the central atom. Then, compare...
