Electronegativity Values and Molecular Geometry

• Electronegativity Difference of < and = 0.4 has a bond type of nonpolar covalent.
• Electronegativity Difference of > and = 2.0 has a bond type of ionic.
• Electronegativity Difference between 0.5 and 1.9 has a bond type of polar covalent.
• Net Dipole Moment

  • Measure of the overall polarity of a molecule.
  • It occurs when a molecule has polar bonds and the individual bond polarities don't cancel each other out due to the molecule's shape or symmetry.
