Which of the following products is obtained by the oxidation of propionaldehyde

Options

A. Acetic acid
B. Formic acid and acetic acid
C. Propanoic acid
D. n-propyl alcohol

Explanation

To solve the question regarding the oxidation of propionaldehyde, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Structure of Propionaldehyde**:
Propionaldehyde is an aldehyde with the chemical formula C3H6O. Its structural formula can be represented as:
\[ \text{CH}_3\text{CH}_2\text{CHO} \]
This shows that propionaldehyde has three carbon atoms.

2. **Understand the Oxidation Process**:
When aldehydes are oxidized, they typically convert into carboxylic acids. The general reaction for the oxidation of an aldehyde can be represented as:
\[ \text{RCHO} \xrightarrow{\text{Oxidizing Agent}} \text{RCOOH} \]
Here, R represents the hydrocarbon chain.

3. **Perform the Oxidation of Propionaldehyde**:
For propionaldehyde (CH3CH2CHO), when it undergoes oxidation, it will convert to propanoic acid (CH3CH2COOH). The reaction can be summarized as:
\[ \text{CH}_3\text{CH}_2\text{CHO} \xrightarrow{\text{Oxidizing Agent}} \text{CH}_3\text{CH}_2\text{COOH} \]

4. **Identify the Product**:
The product of the oxidation of propionaldehyde is propanoic acid, which is a carboxylic acid.

### Final Answer:
The product obtained by the oxidation of propionaldehyde is **propanoic acid (CH3CH2COOH)**.
