Which of the following oxides is/are neutral?

Options

A. `N_(2)O`
B. `CO`
C. `Al_(2)O_(3)`
D. `NO`

Answer

To determine which of the given oxides are neutral, we will analyze each oxide based on its properties:

1. **Understanding Oxide Types**:
- Oxides can be classified into four main categories:
- **Acidic Oxides**: Typically formed from non-metals (e.g., CO2).
- **Basic Oxides**: Typically formed from metals (e.g., Na2O).
- **Amphoteric Oxides**: Can react with both acids and bases (e.g., Al2O3).
- **Neutral Oxides**: Do not exhibit acidic or basic properties (e.g., CO, N2O, NO).

2. **Analyzing Each Oxide**:
- **N2O (Dinitrogen monoxide)**: This oxide is known to be neutral. It does not react with acids or bases.
- **CO (Carbon monoxide)**: This oxide is also classified as neutral. It does not exhibit acidic or basic properties.
- **Al2O3 (Aluminum oxide)**: This oxide is amphoteric. It can react with both acids and bases, thus it is not neutral.
- **NO (Nitric oxide)**: This oxide is considered neutral as it does not show acidic or basic behavior.

3. **Conclusion**:
- The neutral oxides from the given options are **N2O, CO, and NO**.
- The oxide **Al2O3** is amphoteric and not neutral.

**Final Answer**: The neutral oxides are **N2O, CO, and NO**.
