The test used to distinguish alcohols from one another is known as

Options

A. Hinsberg's test
B. 2,4-DNP tes
C. Iodoform test
D. Lucas Lest

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the name of the test used to distinguish between different types of alcohols.

2. **Identifying the Test**: The Lukas test is a well-known method for differentiating between primary, secondary, and tertiary alcohols.

3. **Components of the Lukas Test**: The Lukas test involves the use of zinc chloride (ZnCl2) and hydrochloric acid (HCl).

4. **Mechanism of the Lukas Test**:
- When an alcohol is treated with ZnCl2 and HCl, a carbocation is formed.
- The stability of the carbocation determines the rate of reaction and the time taken for turbidity to appear.
- Tertiary alcohols form stable carbocations quickly, leading to immediate turbidity.
- Secondary alcohols form less stable carbocations, resulting in turbidity after a few minutes.
- Primary alcohols form the least stable carbocations, causing turbidity after a longer duration (around 30 minutes).

5. **Conclusion**: The test used to distinguish alcohols from one another is the Lukas test.

**Final Answer**: The test used to distinguish alcohols from one another is known as the Lukas test.
