The fatty acid which shows reducing property is

Options

A. Acetic acid
B. Ethanoic Acid
C. Oxalic acid
D. Formic acid

Explanation

To determine which fatty acid shows reducing properties, we can analyze the options provided. Here's a step-by-step solution:

### Step 1: Understand the concept of reducing properties
Reducing agents are substances that can donate electrons to another substance, thereby reducing it. In organic chemistry, certain compounds, particularly those with specific functional groups, can act as reducing agents.

### Step 2: Identify the fatty acids
We have four fatty acids to consider:
1. Acetic Acid
2. Ethanoic Acid
3. Oxalic Acid
4. Formic Acid

### Step 3: Analyze each fatty acid for reducing properties
- **Acetic Acid (CH₃COOH)**: This is a simple carboxylic acid that does not exhibit reducing properties.

- **Ethanoic Acid (also CH₃COOH)**: This is another name for acetic acid and similarly does not show reducing properties.

- **Oxalic Acid (C₂H₂O₄)**: While oxalic acid can act as a reducing agent in some reactions, it is primarily known for its ability to form complexes with metal ions rather than being a strong reducing agent.

- **Formic Acid (HCOOH)**: This is the simplest carboxylic acid and is known for its strong reducing properties. It can donate electrons readily, making it a good reducing agent.

### Step 4: Conclusion
Among the fatty acids listed, **Formic Acid** is the only one that shows significant reducing properties.

### Final Answer
The fatty acid which shows reducing property is **Formic Acid**.
