Phenol can be distinguished froma acetic acid by

Options

A. `2,4-`DNP solution
B. Sodium bisulphite test.
C. With `FeCl_(3)` solution
D. Tollen's reagent test.

Explanation

To distinguish phenol from acetic acid, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Compounds**:
- Phenol (C6H5OH) is an aromatic compound with a hydroxyl group (-OH) attached to a benzene ring.
- Acetic acid (CH3COOH) is a simple carboxylic acid.

2. **Identify the Test**:
- We will use Ferric Chloride (FeCl3) solution as the reagent for the test.

3. **Perform the Test**:
- Add a few drops of FeCl3 solution to separate samples of phenol and acetic acid.

4. **Observe the Results**:
- **For Phenol**: The addition of FeCl3 will result in a color change, typically producing a violet or purple color due to the formation of a phenol-iron complex.
- **For Acetic Acid**: There will be no color change; the solution will remain yellowish or unchanged, indicating a negative result.

5. **Conclusion**:
- Since phenol gives a positive test (color change) with FeCl3 and acetic acid gives a negative test (no color change), we can distinguish between the two compounds based on this reaction.

### Final Answer:
Phenol can be distinguished from acetic acid by using FeCl3 solution, where phenol gives a positive test (color change) and acetic acid gives a negative test (no color change).
