Although models cannot show this simply, for molecules like NF3 (whose Lewis structure you drew on the previous page), the actual bond angles may not exactly equal the angles predicted by VSEPR theory. For example, the F-N-F bond angles in NF3 are less than the 109.5° tetrahedral angle. Why do you think this might be so? 2.
