What are the main postulates of Valence Shell Electron Pair Repulsion (VSEPR) theory?

Explanation

(i) The shape of a molecule depends upon the no. of electron pairs around the centra atom.
(ii) There is a repulsive force between the electron pairs, which tend to repel one another.
(iii) The electron pairs in space tend to occupy such positions that they are at maximum distance, so that the repulsive force will be minimum.
(iv) A multiple bond is treated as ifit 1s a single bond and the remaining electron pairs which onstitute the bond may be regarded as single super pair.
