determine which statement is true or false and why. "a molecule with polar bonds must always be a polar molecule", "symmetrical molecules ar usually nonpolar", "two molecules can contain polar bonds but have different overall polarities", "bond polarity and molecular polarity are the same thing"

Answer

  1. A molecule with polar bonds must always be a polar molecule: False. A molecule can have polar bonds but still be nonpolar if the molecular geometry allows for the dipoles to cancel each other out, such as in carbon dioxide (CO2).
  2. Symmetrical molecules are usually nonpolar: True. Symmetrical molecules often have dipoles that cancel out, resulting in no overall dipole moment, making them nonpolar.
  3. Two molecules can contain polar bonds but have different overall polarities: True. The overall polarity of a molecule depends on both the individual bond polarities and the molecular geometry, which can lead to different polarities.
  4. Bond polarity and molecular polarity are the same thing: False. Bond polarity refers to the polarity of individual bonds within a molecule, while molecular polarity refers to the overall polarity of the entire molecule, which is influenced by both bond polarities and molecular shape.
