VSEPR THEORY

What is VSEPR Theory?

• Each group of valence electrons around a central atom is located as close as possible from the others in order to maximise repulsions.

• Each group of valence electrons around a central atom is located as far as possible from the others in order to minimize repulsions.

• Each group of valence electrons around a central atom is located as close as possible from the others in order to minimize repulsions.
