Dipole moment of CO₂ is:
AZero (linear, symmetric)
BEqual to bond dipole
CVariable
DMaximum
Answer & Solution
Correct answer: A. Zero (linear, symmetric)
CO₂ is LINEAR (O=C=O). The two C=O bond dipoles point in opposite directions and cancel exactly. Net dipole moment = 0, despite having polar bonds. Compare with H₂O where bent geometry gives nonzero net dipole.
