Which formula represents a non polar molecule with polar covalent bonds

CO2

Explanation:

Even though the question has no options, but we shall adopt a holistic approach in answering the question.

Now, the polarity of a molecule does not only depend on the presence of polar covalent bonds but on the direction of the net dipole moments of all the polar covalent bonds present. The net dipole moment also depends on the shape of the molecule.

Let us take the CO2 example. The molecule is linear with two polar covalent C-O bonds. The orientation of the dipole moments are opposite beach other hence they cancel out.

Hence the molecule contains polar covalent bonds but remains a nonpolar molecule due to dipoles oriented in opposite directions. Other molecules can also be used as examples.
