The compound that is NOT a common component of photochemical smog is :
  1. (A)
  2. (B)(see structure)
  3. (C)
  4. (D)✓ Correct

Answer: (D)

Solution

Photochemical smog forms when sunlight acts on nitrogen oxides and hydrocarbons, and its hallmark species are ozone , peroxyacetyl nitrate (PAN) and aldehydes such as acrolein . The chlorofluorocarbon attacks stratospheric ozone but plays no part in forming ground-level photochemical smog, so it is the odd one out.
