Afault in which the rocks on either side of the fault move sideways past each other is a a. strike-slip fault. Polar "In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment. Indicate the VSEPR geometry about the central atom. Molecular Geometry. this requires 1.91 kcal of energy. This compound is also known as Tellurium Dioxide. The hydrogen bond is stronger than the dipole dipole interaction, thus it requires an higher amount of heat energy to break the hydrogen bond which hold the molecules of the water together, that is why water has an higher boiling point than ammonium ion even though they have the same molecular mass and electronic shape. Transcription. It is easy to understand the molecular geometry of a given molecule by using the molecular formula or VSEPR model.
