CO2 Lewis Structure Polar or Nonpolar: CO 2 has a linear, symmetrical structure with polar C-O bonds. However, due to symmetry, the bond polarities cancel out, making CO 2 a nonpolar molecule.

Covalent Bonds: Students learn how to predict the shape of a molecule based on the electron dot diagram and to explain what determines molecular polarity. Intermolecular forces are also described ...
