Fluorine is the best oxidising agent because it has

Options

A. highest electron afffinity
B. highest reduction potential
C. highest oxidation potential
D. lowest electron affinity.

Explanation

To solve the question, "Fluorine is the best oxidising agent because it has," we will analyze the properties of fluorine and its reduction potential.

### Step-by-Step Solution:

1. **Understanding Oxidizing Agents**:
- An oxidizing agent is a substance that gains electrons in a chemical reaction and is reduced. The stronger the oxidizing agent, the more readily it accepts electrons.

2. **Reduction Potential**:
- The strength of an oxidizing agent can be quantified by its standard reduction potential (E°). The higher the E° value, the stronger the oxidizing agent.

3. **Fluorine's Reduction Potential**:
- Fluorine (F2) has the highest standard reduction potential among all elements. The standard reduction potential for the half-reaction:
\[ \text{F}_2 + 2e^- \rightarrow 2\text{F}^- \]
is +2.87 V (approximately +2.9 V).

4. **Conclusion**:
- Since fluorine has the highest standard reduction potential, it means that it can easily accept electrons, making it the best oxidizing agent.

5. **Final Answer**:
- Therefore, the correct answer is that fluorine is the best oxidizing agent because it has the highest standard reduction potential.
