Which one of the following oxides is neutral ?

Options

A. SrO
B. `AI_(2)O_(3)`
C. `CO_(2)`
D. CO

Explanation

To determine which oxide is neutral among the given options, we need to classify the oxides based on their chemical behavior. Here’s a step-by-step solution:

### Step 1: Understand the Types of Oxides
Oxides can be classified into three main categories based on their reactivity:
1. **Basic Oxides**: These are typically metal oxides that react with acids to form salts and water. Example: Strontium oxide (SrO).
2. **Acidic Oxides**: These are usually non-metal oxides that react with bases. Example: Silicon dioxide (SiO2).
3. **Amphoteric Oxides**: These can react with both acids and bases. Example: Aluminum oxide (Al2O3).
4. **Neutral Oxides**: These do not react with either acids or bases. Example: Carbon monoxide (CO).

### Step 2: Analyze the Given Oxides
- **Strontium Oxide (SrO)**: This is a basic oxide because it reacts with acids.
- **Aluminum Oxide (Al2O3)**: This is an amphoteric oxide as it can react with both acids and bases.
- **Silicon Dioxide (SiO2)**: This is an acidic oxide as it reacts with bases.
- **Carbon Monoxide (CO)**: This is a neutral oxide as it does not react with either acids or bases.

### Step 3: Identify the Neutral Oxide
From the analysis:
- The only oxide that does not react with acids or bases is Carbon Monoxide (CO).

### Conclusion
Thus, the oxide that is neutral among the given options is **Carbon Monoxide (CO)**.
