___CH4 a. linear
___PCl3 b. pyramidal
___BeBr2 c.tetrahedral
___H2O d.bent
___BF3 e.planar triangular

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 ...
