Which theory proposes that the stereochemistry of an atom in a molecule is determined primarily by the repulsive interactions amongst all the electron pairs in its valence shell?
Lewis theory
VSEPR theory
Coordination theory
Hybridization theory
The valence shell electron pair repulsion (VSEPR) theory is a model used to predict 3-D molecular geometry based on the number of valence shell electron bond pairs among the atoms in a molecule or ion. This model assumes that electron pairs will arrange themselves to minimize repulsion effects from one another.
