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?

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.
