A good example of a nonpolar molecule that contains polar bonds is carbon dioxide (Figure \(\PageIndex{3a}\)). Although the carbon and oxygen differ in their electronegativity due to which C=O bond is polar, the polarity of both opposite C=O bonds get canceled by each other due to symmetrical shape and result in a nonpolar molecule with zero dipole moment. We conclude that molecular geometry is determined by minimizing the mutual repulsion of the valence shell electron pairs. Examples: In a water molecule, H 2 O two of the central oxygen atom’s valence electrons form two bond pairs with the hydrogen atoms, while the remaining four electrons form two lone pairs.
