CO₂ and SO₂ are two compounds. Which of the following best describes these two compounds?
Correct answer: C. CO2 in linear and non-polar SO2 is angular and polar
- A. Both CO2 and SO2 are linear and non polar
- B. CO2 is angular and polar SO2 is linear and non-polar
- C. CO2 in linear and non-polar SO2 is angular and polar
- D. Both CO2 and SO2 are angular and polar
Explanation
In CO2, two oxygen atoms are bonded with carbon atom and the geometry will be linear.O=C=OBut, in SO2, although 2 oxygen atoms are bonded with sulphur but due to presence of lone pair on sulphur, the geometry will be angular ( 2 bond pairs and 1 lone pair.)In CO2, both oxygen atoms exert equal and opposite force on carbon atoms, hence cancel out each other's effect. So, CO2 is non - polar.While, in SO2, cancellation does not occur, so SO2 is polar in nature.Hence, option C is correct.

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.
