Resource Feature | September 2017 Increasing Student Comprehension of VSEPR Theory
In the activity described in this article, students construct physical models of molecular shapes. However, students are not told what the preferred arrangements of electron pair domains are. Instead, they derive the arrangements. Students are given the opportunity to conceptualize what is happening when one electron pair domain acts upon another, and to understand how those interactions result in the molecular geometries predicted by VSEPR theory. As an outcome of examining the physical basis of the VSEPR model, students should have a much better grasp of the implications of electron pair repulsions on molecular shape, and should be better able to understand, communicate, and apply that understanding.
