Which of the following oxide is neutral ?

Options

A. CO
B. Sn`O_(2)`
C. ZnO
D. `SiO_(2)`

Answer

To determine which of the following oxides is neutral, we need to understand the classification of oxides based on their behavior with acids and bases.

### Step-by-Step Solution:

1. **Understanding Neutral Oxides**:
- Neutral oxides are those that do not exhibit acidic or basic properties. This means they do not react with acids or bases to form salts.
- Examples of neutral oxides include Nitric Oxide (NO), Carbon Monoxide (CO), and Dinitrogen Oxide (N2O).

2. **Identifying Oxides**:
- We need to look at the options provided (though not listed in the question) and identify their nature (acidic, basic, or neutral).
- Metal oxides are typically basic, while non-metal oxides are generally acidic. Some oxides, like those of certain metals (e.g., Copper, Zinc, Tin, Lead, Beryllium, Aluminum), can be amphoteric, meaning they can act as either an acid or a base.

3. **Analyzing Given Options**:
- If one of the options is Carbon Monoxide (CO), it is a neutral oxide.
- If another option is Nitric Oxide (NO), it is also a neutral oxide.
- If there are options like SnO2 (Tin Oxide) or ZnO (Zinc Oxide), these are amphoteric and not neutral.
- Therefore, we need to select the oxide that is confirmed to be neutral.

4. **Conclusion**:
- Based on the examples and definitions, if Carbon Monoxide (CO) or Nitric Oxide (NO) is among the options, then they are the correct answers as neutral oxides.

### Final Answer:
The neutral oxide from the options provided is Carbon Monoxide (CO) or Nitric Oxide (NO), depending on the specific options given.
