The dipolar moment of CO2 is zero because it is:
Correct answer: B. Linear
- A. Angular
- B. Linear
- C. Triatomic
- D. Pyramidal
- E. CO is polar
Explanation
The correct answer is option (B): Linear. The dipole moment of a molecule depends on the polarity of its bonds and the molecular geometry. In the case of CO2 (carbon dioxide), it has a linear molecular geometry due to the arrangement of the atoms. The carbon atom is located in the centre, with two oxygen atoms bonded to it on opposite sides.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
