Unsaturation in the organic compound can be tested by the help of

Options

A. Baeyer's test
B. Fehling test
C. chlorination reaction
D. dehydration reaction

Explanation

To determine the unsaturation in an organic compound, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Unsaturation**:
- Unsaturation refers to the presence of double or triple bonds in an organic compound. This means that the compound has fewer hydrogen atoms than a saturated compound (which only has single bonds).

2. **Identify the Test**:
- The test used to detect unsaturation is known as **Baeyer's test**.

3. **Prepare Baeyer's Reagent**:
- Baeyer's reagent is an alkaline solution of potassium permanganate (KMnO4). This reagent is typically purple or pink in color.

4. **Conduct the Test**:
- Add a few drops of Baeyer's reagent to the organic compound you want to test for unsaturation.

5. **Observe the Color Change**:
- If the organic compound is unsaturated (contains double or triple bonds), the pink color of the Baeyer's reagent will disappear, turning colorless. This indicates the presence of unsaturation.
- If the compound is saturated (contains only single bonds), the pink color will remain unchanged.

6. **Conclusion**:
- Based on the color change, you can conclude whether the organic compound is unsaturated or not. If the color changes to colorless, the compound is unsaturated; if it remains pink, the compound is saturated.

### Final Answer:
The unsaturation in the organic compound can be tested by the help of **Baeyer's test**.
