A : Zn dissolve in excess of NaOH solution so as to give `H_(2)`
R : `Zn(OH)_(2)` is neutral is nature.

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 explanantion of the assertion, then mark (2)
C. If assertion is true statements but Reason is false, then mark (3)
D. If both Assertion and Reason are false statements, then mark (4)

Answer

To solve the question, we need to analyze both the assertion (A) and the reason (R) provided:

**Assertion (A):** Zn dissolves in excess of NaOH solution to give H₂.

**Reason (R):** Zn(OH)₂ is neutral in nature.

### Step-by-Step Solution:

1. **Understanding the Reaction:**
- When zinc (Zn) is added to an excess of sodium hydroxide (NaOH), it reacts to form sodium zincate (Na₂ZnO₂) and hydrogen gas (H₂).
- The balanced chemical equation for this reaction is:
\[ \text{Zn} + 2\text{NaOH} \rightarrow \text{Na}_2\text{ZnO}_2 + \text{H}_2 \]
- This confirms that the assertion (A) is true.

2. **Analyzing the Nature of Zn(OH)₂:**
- Zinc hydroxide (Zn(OH)₂) is known to be amphoteric, meaning it can react with both acids and bases.
- When zinc hydroxide is dissolved in water, it does not behave as a neutral substance. Instead, it has a pH of around 8.88, indicating that it is basic in nature.
- Therefore, the reason (R) stating that Zn(OH)₂ is neutral is false.

3. **Conclusion:**
- The assertion (A) is true, while the reason (R) is false. Thus, the overall statement is that the assertion is correct, but the reason is incorrect.

### Final Answer:
- Assertion (A) is true.
- Reason (R) is false.
