Which of the following statement is wrong?

Options

A. `F_(2)` is the strongest oxidising agent as its reduction potential is highest
B. Li is the weakest reducing agent as its reduction potential is low
C. Li is the strongest reducing agent as its reduction potential is low
D. `F^(-)` ion does not show reducing property when react with metal ion

Answer

To determine which statement is wrong regarding the electrochemical properties of elements, let's analyze each option step by step.

### Step 1: Analyze the first statement
**Statement 1:** F2 is the strongest oxidizing agent as its reduction potential is highest.

- The standard reduction potential (E°) for F2 is +2.85 V, which is indeed the highest among common oxidizing agents. Therefore, this statement is **correct**.

### Step 2: Analyze the second statement
**Statement 2:** Lithium is the weakest reducing agent as its reduction potential is low.

- The standard reduction potential (E°) for lithium is -3.05 V. A lower (more negative) reduction potential indicates a stronger reducing agent, not a weaker one. Therefore, this statement is **incorrect**.

### Step 3: Analyze the third statement
**Statement 3:** Lithium is the strongest reducing agent as its reduction potential is low.

- Since lithium has the lowest reduction potential (-3.05 V), it is indeed the strongest reducing agent. Therefore, this statement is **correct**.

### Step 4: Analyze the fourth statement
**Statement 4:** F- ion does not show reducing properties when reacting with metal ions.

- The F- ion does not act as a reducing agent because it is already in a reduced state. When it reacts with metal ions (like Na+), there is no electron transfer. Therefore, this statement is **correct**.

### Conclusion
After analyzing all statements:
- The **incorrect statement** is **Statement 2**: "Lithium is the weakest reducing agent as its reduction potential is low."

### Final Answer
The wrong statement is **Option B**.
