Which of the following statements about photochemical smog is wrong ?

Options

A. It has concentration of oxidising agents
B. It has low concetration of oxdising agent
C. It can be controlled by controlling the release `NO_(2)`, hydrocarbon, ozone etc.
D. Plantation of some plants like pinus helps in controlling phochemical smog

Explanation

To determine which statement about photochemical smog is wrong, we will analyze each statement based on our understanding of photochemical smog.

### Step-by-Step Solution:

1. **Understanding Photochemical Smog**:
- Photochemical smog is commonly referred to as "summer smog" because it typically occurs during the summer months. It is formed when sunlight reacts with nitrogen dioxide (NO2) and organic compounds, such as aldehydes and ketones.

2. **Formation of Photochemical Smog**:
- The reactions involved include:
- Sunlight (UV light) + Nitrogen Dioxide (NO2) + Organic Compounds → Photochemical Smog.
- This process results in the formation of harmful airborne particles and ground-level ozone (O3).

3. **Analyzing the Statements**:
- **Statement 1**: "It has concentration of oxidizing agents."
- This statement is correct because photochemical smog contains ozone (O3), which is a strong oxidizing agent.

- **Statement 2**: "It has low concentration of oxidizing agents."
- This statement is incorrect. Photochemical smog actually has a high concentration of oxidizing agents, primarily due to the presence of ozone.

- **Statement 3**: "It cannot be controlled by controlling the release of NO2 hydrocarbons ozone."
- This statement is also incorrect. Photochemical smog can be controlled by reducing the emissions of NO2 and hydrocarbons, which are precursors to its formation.

- **Statement 4**: "Plantation of plants like Pinus can help control photochemical smog."
- This statement is correct. Plants like Pinus can absorb NO2 and other organic compounds, thus helping to reduce their concentrations in the atmosphere and mitigate photochemical smog.

4. **Conclusion**:
- The wrong statement among the options provided is **Statement 2**: "It has low concentration of oxidizing agents."
