VSEPR Worksheet
AP Chemistry
Learning Objectives: Students will learn about different VSEPR shapes, hybrid orbital diagrams and the effect of the lone pairs on
those shapes using molecular model kits.
Materials:
 Molecular Model Kits
Procedures: Make model of the molecule using the molecular model kit and complete the following table. In addition, please show all steps
for drawing the VSEPR structure of each of these molecules/species at the end of the paper.

Discussion Questions:
1. How do the bond angles differ on a molecule with non-bonding electron pairs around the central atom?
2. Name two elements that can be central atoms with less than a full octet.
3. Predict the bond angles around the central atom in the molecule, ClF4+ ion.
4. Why does the molecule, BF3, contain only single bonds giving boron an incomplete octet?
