CHEM1611 - Resources for Week 3


Topics and Learning Outcomes

  • The Shapes of Molecules
    •  work out the number of bonding and non-bonding pairs from the Lewis structure of a molecule
    •  predict the distribution of these pairs around an atom
    •  place any lone pairs in appropriate positions to minimize the overall electron pair repulsion
    •  predict and describe the molecular shape
    •  predict the hybridization around C, N and O atoms in organic compounds
    •  relate electronegativity to bond polarity
    •  relate bond polarity and molecular shape to the existence of a molecular dipole moment
  • Intermolecular forces
    •  describe the different kinds of intermolecular forces that exist
    •  identify which intermolecular forces are present and which are more important between different molecules
    •  relate variations in melting and boiling points in related compounds to their intermolecular forces
