If there are only bond pairs in the valence shell around the central atom it has regular geometry but when there are lone pairs also in the valence shell, the geometry becomes irregular due to increase in force of repulsion. Thus the Molecular geometry is determined by the number and nature of pairs of electrons surrounding the central atom. The repulsive forces between various types of electron pairs are in the order ![]() These electron pairs extend a repulsion force on one another and so lie as far apart from one another as possible so that the force of repulsions are minimized. There is a central atom, which is surrounded by bonded electron pairs or lone pairs of electron and shared pair of electrons in its valence shell. This theory is known as valence shell electron pair repulsion theory, which determines the shape and molecular geometry in a polyatomic molecule. For molecules that contain only single bonds.
