Question

classify as polar or nonpolar. co2

Explanation:

Step1: Analyze electronegativity difference

Oxygen is more electronegative than carbon. In $CO_2$ (O = C = O), there are polar - bonds between C and O due to electronegativity difference.

Step2: Consider molecular geometry

$CO_2$ has a linear geometry. The bond - dipoles of the two C=O bonds are equal in magnitude but opposite in direction.

Step3: Determine net dipole moment

The two equal and opposite bond - dipoles cancel each other out, resulting in a net dipole moment of zero for the $CO_2$ molecule.

Answer:

Nonpolar molecule
