What is the relationship between molecular polarity and bond polarity?

Molecular polarity is determined by the overall arrangement of polar bonds within a molecule. If a molecule has polar bonds that are arranged symmetrically, the molecule is nonpolar. However, if the polar bonds are arranged asymmetrically, the molecule is polar. Therefore, the relationship between molecular polarity and bond polarity is that the presence and arrangement of polar bonds within a molecule determine its overall polarity.
