Test Unit 6 Chemical Structure

CO₂ has no symmetrical shape to it, making it nonpolar.

Bond polarity (or dipole moment) between C and O atoms cancel due to symmetry.

Bond polarity (or dipole moment) between C and O atoms do not cancel and is stronger to the left side of the molecule.

Electronegativity of C and O atoms are the same therefore makes the molecule nonpolar.
