D. molecular shapes can not be explained

5.
VSEPR theory explains ______.

1. What are the molecular shapes of?
Methane (CH4)

This is a tetrahedral structure and this structure is in your book along with all the other VESPER theory structures.

You don't have your own chemistry book?

[neodarwinian]

You should know this is a tetrahedral structure and the VESPER theory is well explained in your chem book

5.
VSEPR theory explains ______.

This should be obvious as we live in a three dimensional world.
