Assertion `:-` `Mn_(2)O_(7)` is acidic but `MnO` is basic.
Reason `:-` `Mn^(+7)` is strong oxidising agent than `Mn^(+2)`

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark (1)
B. If both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark (2)
C. If Assertion is true statement but Reason is false, then mark (3)
D. If both Assertion and Reason are false statements, then mark (4)

Answer

To analyze the assertion and reason provided in the question, we will break down the concepts step by step.

### Step 1: Understanding the Assertion
The assertion states that \( \text{Mn}_2\text{O}_7 \) is acidic while \( \text{MnO} \) is basic.

- **Explanation**:
- \( \text{Mn}_2\text{O}_7 \) contains manganese in the +7 oxidation state. Compounds in higher oxidation states of transition metals tend to be acidic because they can accept electrons (Lewis acids).
- Conversely, \( \text{MnO} \) contains manganese in the +2 oxidation state. Compounds in lower oxidation states are typically basic since they can donate electrons (Lewis bases).

### Step 2: Understanding the Reason
The reason states that \( \text{Mn}^{+7} \) is a stronger oxidizing agent than \( \text{Mn}^{+2} \).

- **Explanation**:
- The higher the oxidation state, the greater the tendency of the element to gain electrons and thus act as an oxidizing agent. Therefore, \( \text{Mn}^{+7} \) is indeed a stronger oxidizing agent than \( \text{Mn}^{+2} \).

### Step 3: Evaluating the Relationship
Now we need to determine if the reason correctly explains the assertion.

- **Analysis**:
- While both statements are true (the assertion and the reason), the reason does not directly explain why \( \text{Mn}_2\text{O}_7 \) is acidic and \( \text{MnO} \) is basic. The acidity of \( \text{Mn}_2\text{O}_7 \) is due to its higher oxidation state, while the basicity of \( \text{MnO} \) is due to its lower oxidation state. The strength of the oxidizing agent does not directly correlate to the acidity or basicity of the oxides.

### Conclusion
Based on the analysis:
- The assertion is correct: \( \text{Mn}_2\text{O}_7 \) is acidic and \( \text{MnO} \) is basic.
- The reason is also correct: \( \text{Mn}^{+7} \) is a stronger oxidizing agent than \( \text{Mn}^{+2} \).
- However, the reason does not explain the assertion.

Thus, the correct answer is that both the assertion and reason are true, but the reason is not the correct explanation of the assertion.

### Final Answer
Both assertion and reason are correct, but the reason is not the correct explanation of the assertion.
