Question

A molecule of carbon dioxide (CO2) contains two polar covalent bonds. Why is the molecule nonpolar?

Answer 1

The molecule has a symmetrical distribution of charge.

Step-by-step explanation:

A CO2 molecule is nonpolar because the molecule is linear and has a symmetrical distribution of charge as seen in this diagram:

Answer 2

The molecule is non-polar, because the difference in electronegativity between the two sides of the structure equals 0. The electronegativity difference between O (3.5) and C(2.5) is 1 and also on the other side, cancelling each other.
