Which of the following is not correctly matched?

Options

A. Acidic oxides - `P_(2)O_(5), NO_(2), Cl_(2)O_(7)`
B. Basic oxides - `Na_(2)O, CaO, MgO`
C. Neutral oxides - `CO_(2), CO, BeO`
D. Amphoteric oxides - `ZnO, SnO, Al_(2)O_(3)`

Explanation

To solve the question "Which of the following is not correctly matched?" we need to analyze the given examples of oxides and determine whether they are neutral, acidic, or amphoteric.

### Step 1: Understand the definition of neutral oxides
Neutral oxides are oxides that do not react with either acids or bases. This means they do not exhibit acidic or basic properties.

### Step 2: Identify the examples given
The examples provided in the question are:
1. Carbon Dioxide (CO₂)
2. Carbon Monoxide (CO)
3. Beryllium Oxide (BeO)

### Step 3: Analyze each oxide
- **Carbon Dioxide (CO₂)**: This oxide reacts with bases, indicating that it is an acidic oxide, not a neutral oxide.
- **Carbon Monoxide (CO)**: This is a neutral oxide as it does not react with acids or bases.
- **Beryllium Oxide (BeO)**: This oxide is amphoteric, meaning it can react with both acids and bases.

### Step 4: Determine which is not correctly matched
From the analysis:
- Carbon Dioxide (CO₂) is incorrectly matched as a neutral oxide because it is actually an acidic oxide.
- Carbon Monoxide (CO) is correctly matched as a neutral oxide.
- Beryllium Oxide (BeO) is incorrectly matched as a neutral oxide because it is amphoteric.

### Conclusion
The oxides that are incorrectly matched as neutral oxides are Carbon Dioxide (CO₂) and Beryllium Oxide (BeO). Therefore, the answer to the question is that the option containing Carbon Dioxide (CO₂) is not correctly matched.

**Final Answer**: Option C (Carbon Dioxide) is not correctly matched as a neutral oxide.
