Which of the following oxide does not give any oxyacid in aqueous solution ?

Options

A. `N_(2)O_(5)`
B. `Cl_(2)O_(7)`
C. `CrO_(3)`
D. `N_(2)O`

Explanation

To determine which oxide does not give any oxyacid in aqueous solution, we first need to understand what an oxyacid is. An oxyacid is defined as an acid that contains oxygen, hydrogen, and another element, where at least one hydrogen atom is bonded to an oxygen atom, allowing it to donate H⁺ ions in solution.

### Step-by-Step Solution:

1. **Identify the Oxides**:
We need to analyze the given oxides. Let's assume the options are:
- A. N₂O
- B. CrO₃
- C. N₂O₅
- D. HClO₄

2. **Determine the Nature of Each Oxide**:
- **N₂O (Dinitrogen monoxide)**: This oxide is neutral and does not exhibit acidic properties. It does not react with water to form an oxyacid.
- **CrO₃ (Chromium trioxide)**: This oxide is acidic and reacts with water to form chromic acid (H₂CrO₄), which is an oxyacid.
- **N₂O₅ (Dinitrogen pentoxide)**: This oxide is also acidic and reacts with water to form nitric acid (HNO₃), which is an oxyacid.
- **HClO₄ (Perchloric acid)**: This is already an oxyacid and does not need to react with water.

3. **Conclusion**:
Among the given oxides, only N₂O does not produce any oxyacid when dissolved in water. Therefore, the answer to the question is:
- **N₂O (Option A)** does not give any oxyacid in aqueous solution.

### Final Answer:
The oxide that does not give any oxyacid in aqueous solution is **N₂O**.
