The VSEPR (Valence shell electron pair repulsion) theory is concerned with the shapes of covalent molecules. It postulates:
· The shape of a molecule depends upon the number of valence shell electron pairs (bonded or non-bonded) around the central atom.
· Pairs of electrons in the valence shell tend to repel each other as their electron clouds are negatively charged.
· The electron pairs tend to occupy those positions in space, which minimize repulsions and thus maximize distance from one another.
· The valence shell is taken as a sphere with the electron pairs localizing on the spherical surface at maximum distance from one another.
· A multiple bond is treated as a single electron pair and the two or three electron pairs of a multiple bond are treated as a single super pair.
· The VSEPR model is applicable to any such structure where two or more resonance structures can represent a molecule.
