What is VSEPR Theory?

Back

VSEPR Theory (Valence Shell Electron Pair Repulsion Theory) is a model used to predict the geometry of individual molecules based on the repulsion between the pairs of valence electrons surrounding an atom.

How does VSEPR Theory explain the shape of molecules?

Back

It explains that the shape of a molecule is determined by the repulsion between electron pairs, which causes them to arrange themselves as far apart as possible.
