Visualization: Molecular Structure and the VSEPR Theory

Chemistry / April 23, 2015 / No Comments /
An exploration of the concepts of this theory and how to use balloons to build geometric models of several types of molecules.

” This theory has since become what we now know as the valence-shell electron-pair repulsion model (VSEPR), which states that the geometric arrangement of electron pairs around a central atom are the result of electrostatic repulsion between electron pairs. The basic principle of this is that repulsion between electrons in bonding pairs and lone pairs causes them to remain as far apart as geometrically possible. Thus, the arrangement that a molecule ultimately assumes is the one that best minimizes repulsion.”
