D. `CH_(3)COCH_(3)`

Answer

To solve the question of what happens when ethyl alcohol (ethanol) is oxidized with pyridinium chlorochromate (PCC), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Compound**:
- Ethyl alcohol is also known as ethanol, with the chemical formula \( \text{C}_2\text{H}_5\text{OH} \) or \( \text{CH}_3\text{CH}_2\text{OH} \).

2. **Understand the Oxidizing Agent**:
- Pyridinium chlorochromate (PCC) is a mild oxidizing agent. It is commonly used in organic chemistry to oxidize alcohols.

3. **Determine the Type of Alcohol**:
- Ethanol is a primary alcohol because the hydroxyl group (-OH) is attached to a carbon that is connected to only one other carbon atom.

4. **Oxidation Reaction**:
- When a primary alcohol is oxidized by a mild oxidizing agent like PCC, it is converted into an aldehyde.
- The oxidation of ethanol can be represented as follows:
\[ \text{C}_2\text{H}_5\text{OH} \xrightarrow{\text{PCC}} \text{C}_2\text{H}_4\text{O} + \text{H}_2\text{O} \]
- Here, ethanol (\( \text{C}_2\text{H}_5\text{OH} \)) is oxidized to acetaldehyde (\( \text{C}_2\text{H}_4\text{O} \)), also known as ethanal.

5. **Final Answer**:
- Therefore, when ethyl alcohol (ethanol) is oxidized with PCC, it gives acetaldehyde (ethanal).

### Conclusion:
The correct answer is that ethyl alcohol, when oxidized with PCC, yields acetaldehyde.
