The irritant red haze in the traffic and congested places is due to oxides of ,

Options

A. Nitrogen
B. Carbond
C. Sulphur
D. 1,2,3

Answer

**Step-by-Step Solution:**

1. **Identify the Cause of Red Haze:**
The red haze observed in traffic and congested areas is primarily due to the presence of certain pollutants in the atmosphere.

2. **Determine the Specific Pollutants:**
The main pollutants responsible for the red haze are oxides of nitrogen, particularly nitrogen dioxide (NO2).

3. **Understanding the Nature of Nitrogen Dioxide:**
Nitrogen dioxide is a reddish-brown gas that is highly toxic. Its color contributes to the reddish appearance of the haze.

4. **Source of Nitrogen Oxides:**
The primary source of nitrogen oxides (NOx) in urban areas is the combustion of fossil fuels in vehicles, such as cars and trucks.

5. **Chemical Reaction Involved:**
When nitrogen monoxide (NO) is emitted from vehicle exhaust, it can react with oxygen (O2) in the atmosphere to form nitrogen dioxide (NO2):
\[ 2NO + O_2 \rightarrow 2NO_2 \]

6. **Formation of the Haze:**
The nitrogen dioxide then interacts with aerosols and other atmospheric components, leading to the formation of a reddish-brown haze in the air.

7. **Conclusion:**
Therefore, the irritant red haze in traffic and congested places is due to oxides of nitrogen, specifically nitrogen dioxide.

**Final Answer:**
The irritant red haze in the traffic and congested places is due to oxides of nitrogen.
