Assertion : Cu react with HCl & form H_(2) gas
Reason : Cu lies above the hydrogen in electro chemical series

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion & Reason are False.

Explanation

To solve the question, we need to analyze the assertion and the reason provided:

**Assertion:** Copper (Cu) reacts with hydrochloric acid (HCl) to form hydrogen gas (H₂).

**Reason:** Copper lies above hydrogen in the electrochemical series.

### Step-by-Step Solution:

1. **Understanding the Assertion:**
- The assertion states that copper reacts with hydrochloric acid to produce hydrogen gas.
- In reality, copper does not react with hydrochloric acid to produce hydrogen gas. This is because copper is less reactive than hydrogen.

2. **Analyzing the Electrochemical Series:**
- The electrochemical series ranks metals based on their reactivity and their ability to displace hydrogen from acids.
- In this series, metals that are more reactive than hydrogen can displace hydrogen ions (H⁺) from acids to form hydrogen gas.
- Copper is positioned below hydrogen in the electrochemical series, indicating that it is less reactive than hydrogen.

3. **Conclusion on the Assertion:**
- Since copper cannot displace hydrogen ions from HCl, the assertion is incorrect. Therefore, copper does not react with HCl to produce hydrogen gas.

4. **Understanding the Reason:**
- The reason states that copper lies above hydrogen in the electrochemical series.
- This statement is also incorrect, as copper is actually below hydrogen in the electrochemical series.

5. **Final Conclusion:**
- Both the assertion and the reason are incorrect. Thus, the correct answer is that both the assertion and reason are wrong.

### Final Answer:
Both assertion and reason are wrong.
