| Consider the following statements about photochemical smog. |
| 1. It occurs in cool humid climate. |
| 2. It has high concentration of oxidising agents, so is called oxidising smog. |
| 3. It results from the action of sunlight on unsaturated hydrocarbons and nitrogen oxides. |
| Which of the statements) given above is/are correct? |
A) Only 1
B) 1 and 2
C) 2 and 3
D) All of these
Correct Answer: C
Solution :
[c] Photochemical smog is the chemical reaction of sunlight nitrogen oxides and volatile organic compounds in the atmosphere, which leaves airborne particles and ground-level ozone. This obnoxious mixture of air pollutants can include the aldehydes, nitrogen oxides, such as nitrogen dioxide peroxyacyi nitrates, tropospheric ozone, volatile organic compounds. All of these chemicals are usually highly reactive and oxidising.
