Assertion: Acetylene on treatment with alkaline `KMnO_(4)` produce acetaldehyde.
Reason: Alkaline `KMnO_(4)` is a reducing agent.

Options

A. If both assertion and reason are true and the reason is the correct explanation of the assertion
B. If both assertion and reason are true but reason is not the correct explanation of the assertion
C. If assertion is true but reason is false
D. If the assertion and reason both are false

Explanation

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

### Step 1: Analyze the Assertion
The assertion states that acetylene (C2H2) on treatment with alkaline KMnO4 produces acetaldehyde (CH3CHO).

- Acetylene is an alkyne with the formula H-C≡C-H.
- When treated with alkaline KMnO4, an oxidizing agent, acetylene undergoes oxidative cleavage.

**Conclusion for Step 1**: The assertion is **false** because the reaction does not produce acetaldehyde; instead, it leads to the formation of carbon dioxide (CO2) and water (H2O).

### Step 2: Analyze the Reason
The reason states that alkaline KMnO4 is a reducing agent.

- Alkaline KMnO4 is known to act as an oxidizing agent, especially in organic reactions.
- It oxidizes alkynes and alkenes, leading to the cleavage of carbon-carbon bonds.

**Conclusion for Step 2**: The reason is **false** because alkaline KMnO4 is not a reducing agent; it is an oxidizing agent.

### Final Conclusion
Both the assertion and the reason are false. Therefore, the correct answer is that both statements are false.
