Chapter 5, Problem 45E

The Lewis structures for ${\text{CH}}_{\text{4}}{\text{, N}}_{\text{2}}{\text{, and CO}}_{\text{2}}$, along with the corresponding space-filling molecular images, are shown here:

Use Lewis theory and VSEPR theory to draw similar space-filling molecular images of

$\begin{array}{l}\text{a}\text{. CO}\hfill \\ \text{b}{\text{. NH}}_{\text{3}}\hfill \\ \text{c}{\text{. H}}_{\text{2}}\text{S}\hfill \\ \text{d}{\text{. SiH}}_{\text{4}}\hfill \end{array}$
