Presentation Transcript

    1. Molecular Polarity A Bridge from the Molecular World to Macroscopic Properties

    2. Definition Polar Molecule A Molecule with a Positive and Negative Side Dipole Moment A Measure of Molecular Polarity A Nonpolar Molecule will have a Zero Dipole Moment

    3. Why is Polarity Important? Many Properties Depend on Polarity Melting and Boiling Point Surface Tension, Viscosity Reactivity Shapes of Very Large Molecules (Proteins, DNA, RNA) Solubility (e.g., will it dissolve in water)

    4. Requirements A Polar Molecule Requires Polar Bonds And A Molecular Shape that Separates the Positive from the Negative Side
