Question

2. Make a table that shows all the possible molecular shapes and AXE types within each of the 5 geometries: A central atom with 6 electron groups, 5 electron groups, 4 electron groups, 3 electron groups, and 2 electron groups.

• For example, a central atom with 4 electron groups has a tetrahedral electron pair geometry. It includes the following molecular shapes: tetrahedral (AX4E0), trigonal pyramidal (AX3E1), and bent (AX2E2).

• For a central atom with 6 electron groups, consider the following AXE types: AX6E0, AX5E1, AX4E2, AX3E3, and AX2E4. Note: The last two are not in your textbook but can be derived from the VSEPR model.
