Options

A. Dumas method
B. Kjeldahl's method
C. Metathesis method
D. Carius method

Answer

**Step-by-Step Solution:**

1. **Identify the Nobel Prize Winners and Year**: The question mentions that Chauvin, Grubbs, and Schrock won the Nobel Prize in Chemistry in 2005.

2. **Understand the Context of the Award**: The Nobel Prize was awarded for a specific development in the field of chemistry. The options provided are Dumas method, Kijeldaas method, Metathesis method, and Carius method.

3. **Recall the Contribution of the Winners**: The Nobel Prize in Chemistry 2005 was awarded jointly to Yves Chauvin, Robert H. Grubbs, and Richard R. Schrock for their work related to the metathesis method in organic synthesis.

4. **Define Metathesis**: Metathesis refers to a chemical reaction where parts of two molecules exchange places to form new compounds. It can be represented generally as AB + CD → AC + BD.

5. **Provide a Specific Example**: A well-known example of metathesis is the olefin metathesis reaction, where olefins (alkenes) undergo a rearrangement facilitated by a catalyst, leading to the formation of new olefins.

6. **Evaluate the Options**:
- Dumas method: Incorrect.
- Kijeldaas method: Incorrect.
- Metathesis method: Correct.
- Carius method: Incorrect.

7. **Conclude the Answer**: The correct answer is that Chauvin, Grubbs, and Schrock won the 2005 Nobel Prize for the development of the Metathesis method.

**Final Answer**: Metathesis method.
