    To find the shapes of these compounds, you need to first draw Lewis structures of each:

    CH4 has four bonds coming out. This is the most common shape and is tetrahedral, C. Tetrahedral is shaped like a tripod with a stand on top.

    PCl3 is almost like CH4 except that it has a lone pair replacing one of the bonds. If you imagine the tetrahedral ...

    Solution Summary

    This solution explains how to find the shape of several compounds. It also explains how to determine the polarity of compounds.
