Which of the following oxides is neutral ?

Options

A. `N_(2)O_(3)`
B. `N_(2)O_(4)`
C. `N_(2)O_(5)`
D. `N_(2)O`

Explanation

To determine which of the given oxides is neutral, we need to analyze each oxide's behavior when it reacts with water. A neutral oxide does not form an acid or a base upon dissolution in water.

### Step-by-Step Solution:

1. **Identify the Oxides**: The options given are:
- N2O3
- N2O4
- N2O5
- N2O

2. **Analyze N2O3**:
- When N2O3 reacts with water, it forms nitrous acid (HNO2).
- This indicates that N2O3 is an acidic oxide.

3. **Analyze N2O4**:
- N2O4 reacts with water to produce a mixture of nitrous acid (HNO2) and nitric acid (HNO3).
- This also indicates that N2O4 is an acidic oxide.

4. **Analyze N2O5**:
- N2O5 reacts with water to form nitric acid (HNO3).
- This confirms that N2O5 is an acidic oxide.

5. **Analyze N2O**:
- When N2O reacts with water, it forms ammonium nitrate (NH4NO3), which is a salt.
- Since it does not produce an acid or a base, N2O is classified as a neutral oxide.

6. **Conclusion**:
- Among the options, N2O is the only oxide that does not form an acid or a base when dissolved in water, making it the neutral oxide.

### Final Answer:
The neutral oxide among the given options is **N2O** (option D).
