Question

Why is a molecule of CO2 nonpolar even though the bonds between the carbon atom and the oxygen atoms are polar?
(1) The shape of the CO2 molecule is symmetrical.
(2) The shape of the CO2 molecule is asymmetrical.
(3) The CO2 molecule has a deficiency of electrons.
(4) The CO2 molecule has an excess of electrons.

Answer 1

The correct answer is option 1. Carbon dioxide is nonpolar because the shape of the molecule  is symmetrical. It is a linear molecule where the oxygen atoms are symmetrical on each end. CO2 molecule do not have a region of unequal sharing.
