alleryCO2 has polar bonds yet is non-polar overall because:
ACarbon is neutral
BCO2 is ionic
CIt has no dipole moment because oxygen is non-polar
DThe two polar C=O bonds point opposite, cancelling the dipole
Answer & Solution
Correct answer: D. The two polar C=O bonds point opposite, cancelling the dipole
1. Each C=O bond is polar (oxygen attracts shared electrons).
2. CO2 has a linear shape with O=C=O.
3. The two C=O dipoles point in exactly opposite directions.
4. Vector sum of the two dipoles is zero.
5. So CO2 has polar bonds but the molecule is overall non-polar.
