Lesson Plan: VSEPR Chemistry
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to identify the shape of molecules using VSEPR.
Students will be able to
- describe the concept of valence shell electron pair repulsion (VSEPR),
- recall how to draw Lewis structures of simple molecules,
- use VSEPR to predict the shapes and bond angles of simple molecules,
- identify bonding pairs and lone pairs of electrons within molecules,
- apply the AXE Method to assign bonding pairs and lone pairs and determine the steric number,
- link the number of bonding pairs and lone pairs to the shape of the molecule.
Students should already be familiar with
- the formation of ionic and covalent bonds,
- basic knowledge of chemical structures,
- electrostatic forces between like charges,
- the use of solid and dashed wedges to represent bonds in three dimensions.
Students will not cover
- the background or development of VSEPR theory,
- shapes of molecules with steric numbers higher than 6.
