Write any three postulates of VSEPR theory.

Explanation

Postulates of vsepr theory.
The shape of the molecule depends upon the number of valance shell electron pair [bonded and non bonded] Around the central atom.
Valence shell electron pair repel one another as they are negatively charged.
To overcome the repulsion the electron pairs arrange themselves in space such a way that they are far away from one another as possible.
A multiple bond (double or triple) is treated as single electron pair.
