Which one of the following statements regarding photochemical smog is NOT correct?

  1. A
    Photochemical smog does not cause irritation in eyes and throat
  2. B
    Carbon monoxide does not play any role in photochemical smog formation
  3. C
    Photochemical smog is an oxidizing agent in character
  4. D
    Photochemical smog is formed through photochemical reaction involving solar energy.

Solution & Step-by-step Explanation

1. Incorrect: Photochemical smog contains ozone, nitric oxide, acrolein, and PAN (Peroxyacetyl nitrate). These components are powerful eye and throat irritants.2. Correct: Primary precursors are and volatile organic compounds (VOCs). is not a major contributor to smog formation compared to these.3. Correct: Due to high ozone and content, it is oxidizing.4. Correct: Solar energy (UV) is required to dissociate to initiate the reaction.
