Exam points

  • Identify polar bonds before using molecular geometry to combine their dipole vectors and classify a molecule or ion as polar or non-polar.
  • Explain dipole cancellation in a symmetrical molecule or a net dipole in an asymmetrical molecule using bond polarity and geometry.
  • Compare related molecules or isomers by symmetry, shape and vector addition to justify the resulting molecular polarity.
