Don't make these common mistakes with VSEPR! We'll talking about how to determine the shape or geometry of a molecule using the VSEPR rules, for valence shell electron pair repulsion. Unshared electron pairs (also known as lone pairs) are very important for determining geometry, and we'll look at the following shapes: tetrahedral, trigonal planar, trigonal pyramidal, linear, and bent.
