Jet aeroplanes releases pollutants in air called

Options

A. smog
B. photo-chemical oxidants
C. Aerosols
D. Algae and bacteria.

Answer

**Step-by-Step Solution:**

1. **Understanding the Source of Pollution**: Jet aeroplanes operate by burning fuel, which is a significant source of air pollution. This fuel combustion releases various pollutants into the atmosphere.

2. **Identifying the Type of Pollutants**: The pollutants released by jet aeroplanes are primarily in the form of aerosols. Aerosols are tiny particles or droplets suspended in the air.

3. **Composition of Aerosols**: The aerosols produced by jet aeroplanes often contain chlorofluorocarbons (CFCs). CFCs are a group of chemicals that can deplete the ozone layer and contribute to global warming.

4. **Chemical Forms of CFCs**: The specific chemical compounds associated with these aerosols include:
- Dichlorodifluoromethane (CCl2F2)
- Trichlorofluoromethane (CCl3F)

5. **Conclusion**: Therefore, the pollutants released by jet aeroplanes are classified as aerosols, which consist of chlorofluorocarbons.

**Final Answer**: The pollutants released by jet aeroplanes in the air are called aerosols, which consist of chlorofluorocarbons.
