VSEPR Versus
... According to the VSEPR theory, the electrons that are attached to a central atom in a molecule can pivot freely on the atom’s surface to move away from other electrons, which can form bonding pairs, when two electrons are involved in a bond, thus forms “the bond” between atoms. ... Looking at the bonds (sigma and pi) along with the VSEPR, allows us to be able to see the orientation of a molecule more fully, the types of bonds (sigma and pi), in a further understanding of chemical molecules.
