Webmolecular shape, the dipole moments of the bonds do not cancel each other out, therefore, this compound is polar. Figure 5: Lewis Structure and Dipole Moment of Sulfur dioxide . If a central atom with a tetrahedral electron structure has bonded all its valence electrons to four other identical atoms, as in the examplemethane, the WebFor diatomic molecules, there is only one bond, so its bond dipole moment determines the molecular polarity. Homonuclear diatomic molecules such as Br 2 and N 2 have no difference in electronegativity, so their dipole moment is zero. For heteronuclear molecules such as CO, there is a small dipole moment. open houses poway ca
