Imagine being a child and playing with paper dolls. The dolls were essentially two dimensional drawings and came with various paper outfits. Of course, these dolls were no match for the exciting three dimensional toys of today.
Drawing Lewis dot structures for compounds is equally unsatisfying to a chemist. Seeing a molecule drawn out on paper does not really give a scientist much information about its true shape.

In this topic, you will investigate how the VSEPR theory helps to determine the shape of chemical compounds.
