Which of the following element has maximum standard reduction potential?

Options

A. Li
B. K
C. F
D. Cl

Answer

To determine which element has the maximum standard reduction potential, we can follow these steps:

### Step 1: Understand Standard Reduction Potential (SRP)
Standard reduction potential is a measure of the tendency of a chemical species to be reduced, which means to gain electrons. The more positive the SRP, the greater the species' ability to gain electrons and thus act as an oxidizing agent.

### Step 2: Refer to the Electrochemical Series
The electrochemical series lists elements in order of their standard reduction potentials. Elements at the top of the series have higher SRPs and are stronger oxidizing agents, while those at the bottom have lower SRPs and are stronger reducing agents.

### Step 3: Identify Key Elements
In the electrochemical series, we note the following:
- Lithium (Li) has the lowest SRP and is the strongest reducing agent.
- Hydrogen (H⁺) is positioned in the middle.
- Elements like Copper (Cu) have moderate SRPs.
- Fluorine (F₂) is at the top of the series with the highest SRP.

### Step 4: Conclusion
Among the listed elements, Fluorine (F₂) has the maximum standard reduction potential. It is the strongest oxidizing agent due to its high tendency to gain electrons.

### Final Answer
The element with the maximum standard reduction potential is **Fluorine (F₂)**.
