The given substances have to be matched with one of the molecular models that depict its geometry. Concept Introduction: Valence bond theory : The VSEPR theory tells about the shapes of molecules and ions by taking the consideration that the outermost electron pairs are arranged about each atom so that the pairs of electrons are kept at a distance from one molecule to other, thereby minimizing the repulsion of electron-pair.

Definition Definition Theory that explains how individual atomic orbitals with an unpaired electron each, come close to each other and overlap to form a molecular orbital giving a covalent bond. VBT gives a quantum mechanical approach to the formation of covalent bonds with the help of wave functions using attractive and repulsive energies when two atoms are brought from infinity to their internuclear distance.
