Which of the following is used for distinguishing primary , secondary and tertiary alcohols ?

Options

A. Victor Meyer test
B. Beilstein test
C. Hoffmann test
D. Fehling's solution : test

Answer

To determine which test is used for distinguishing primary, secondary, and tertiary alcohols, we can analyze the options provided.

### Step-by-Step Solution:

1. **Understanding the Tests**:
- We need to identify which of the given tests is specifically designed to differentiate between primary, secondary, and tertiary alcohols.

2. **Victor-Meyer Test**:
- The Victor-Meyer test is known for distinguishing between primary, secondary, and tertiary alcohols.
- The procedure involves several reagents: phosphorus (P4) in the presence of iodine, silver nitrite (AgNO2), nitrous acid (HNO2), and alcoholic potassium hydroxide (KOH).
- The results of the test provide different color reactions based on the type of alcohol:
- **Primary Alcohol**: Produces a red color.
- **Secondary Alcohol**: Produces a blue color.
- **Tertiary Alcohol**: Results in a colorless solution.

3. **Other Tests**:
- **Beilstein Test**: This test is used for detecting halides, not alcohols.
- **Hoffman Test**: This is a medical test unrelated to alcohol classification.
- **Felling's Test**: This test is used to differentiate between aldehydes and ketones, not alcohols.

4. **Conclusion**:
- Based on the analysis, the only test that is specifically used for distinguishing primary, secondary, and tertiary alcohols is the **Victor-Meyer test**.

### Final Answer:
The test used for distinguishing primary, secondary, and tertiary alcohols is the **Victor-Meyer test**.
