Question 15

Outline the principles of the VSEPR theory

Answer 15

Electron pairs in the outer shell of the central atom will arrange themselves as far apart as possible so as to minimise repulsion and maximise stability.
The lone pair-lone pair repulsion is greater than lone pair-bond pair repulsion which in turn is greater than bond pair-bond pair repulsion
