PolarityThis should be mostly review…
Part 2: Bond Polarity
Part 3: Molecular Polarity
• 3 or more atoms: • Polarity depends on two things:
• Individual bond polarities
• 3D Shape of molecule
• If a molecule is nonpolar, the bond polarities must be the same (not necessarily nonpolar), AND the shape must be symmetric.
THINK SYMMETRY!!!
