Direct reaction of unsaturated hydrocarbons with either NO or NO2 produces an eye irritating pollutant compound known as________________?
Correct answer: B. Peroxyacetyl nitrate (PAN) or methyl nitrite
- A. Photochemical smog
- B. Peroxyacetyl nitrate (PAN) or methyl nitrite
- C. Benzopyrene
- D. Polyacrylonitrile
Explanation
Nitrogen oxides reacting with unsaturated hydrocarbons in sunlight form secondary oxidants including peroxyacetyl nitrate, or PAN, which strongly irritates the eyes. Photochemical smog is the overall mixture, not the specific eye-irritating compound named here.
