![]() We indicate the phases by shading the orbital lobes different colors. This is one reason why water molecules are polar and have properties such as. In p orbitals, the wave function gives rise to two lobes with opposite phases, analogous to how a two-dimensional wave has both parts above and below the average. This is due to the different numbers of electrons in each molecule and VSEPR (Valence Shell Electron Repulsion) theory. Since the two 2 p orbitals are at right angles to one another, valence bond theory predicts a bent geometry for the water molecule with a bond angle of 90°. Analyzing the computed localized molecular orbitals for each conformation we see that the valence bond electronic structure of water molecule is perfectly. The plus (+) signs indicate the locations of nuclei. Molecular orbital theory (MO theory) provides an explanation of chemical bonding that accounts for the paramagnetism of the oxygen molecule. The valence bond theory of the water molecule describes the two O H bonds as resulting from the overlap of the H 1 s orbitals with the two half-filled 2 p orbitals of the oxygen atom. \): Sigma (σ) and sigma-star (σ*) molecular orbitals are formed by the combination of two s atomic orbitals.
