The catalytic converters fitted in vehicles convert unburnt hydrocarbons into

Options

A. nitrogen gas and water
B. water and carbon dioxide
C. carbon monoxide and nitrogen gas
D. nitric oxide and water

Answer

To solve the question regarding what catalytic converters fitted in vehicles convert unburnt hydrocarbons into, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Catalytic Converters**:
- Catalytic converters are devices installed in the exhaust system of vehicles. Their main function is to reduce harmful emissions from the engine.

2. **Identifying the Reaction**:
- The primary function of a catalytic converter is to facilitate chemical reactions that convert harmful substances into less harmful ones.

3. **Unburnt Hydrocarbons**:
- Unburnt hydrocarbons are a significant pollutant emitted from vehicles. They are the result of incomplete combustion of fuel.

4. **Products of Conversion**:
- The catalytic converter uses catalysts (often made of platinum or palladium) to promote reactions that convert unburnt hydrocarbons into carbon dioxide (CO2) and water (H2O).

5. **Final Answer**:
- Therefore, the unburnt hydrocarbons are converted into carbon dioxide and water vapor.

### Conclusion:
The catalytic converters fitted in vehicles convert unburnt hydrocarbons into carbon dioxide (CO2) and water (H2O).
