If the central atom in a molecular can make 5 bonds, the structure that it makes is based on the trigonal pyramidal shape. If the molecule has lone pairs or unshared electron pairs, the shape could be see saw, Tshaped, or linear. In this video, we'll look at diagrams of the VSEPR shapes, and examine bond angles for each structure.
