1. Bond polarity and molecular shape determine molecular
polarity, which is measured as a dipole moment. True or
False?
2. Molecular shape and polarity can affect physical properties,
such as boiling point, and they play a central role in biological
function. True or False?
3. A molecule with polar bonds is not necessarily a polar
molecule. When bond polarities cancel each other, the molecule is
nonpolar; when they reinforce each other, the molecule is polar.
True or False?
