Question:
What is a VSEPR model? What does VSEPR stand for?



Replies:
VSEPR is a simple model to determine the shapes of molecules based upon the premise that the molecule will tend to place pairs of valence shell electrons (both bonding and nonbonding) as far apart as possible so as to minimize the electron-eleton pair repulsion energy. It works in many simple cases... e.g. it predicts that CO2 is linear and H2O is bent.

Check the bonding chapters in any good college-level general chemistry textbook.
