When an organic compound is present in an aqueous medium and
is less soluble in any organic solvent then, it is separated by :

Options

A. Continuous extraction
B. distillation
C. chromatography
D. sublimation

Answer

To separate an organic compound that is present in an aqueous medium and is less soluble in any organic solvent, the appropriate method is continuous extraction. Here’s a step-by-step explanation of the reasoning behind this choice:

### Step-by-Step Solution:

1. **Understanding the Problem**:
- The organic compound is present in an aqueous medium.
- It is less soluble in any organic solvent, which means it does not readily dissolve in organic solvents.

2. **Evaluating Separation Techniques**:
- **Distillation**: This method is used for separating volatile liquids based on their boiling points. Since the compound is less soluble in organic solvents, distillation is not suitable.
- **Chromatography**: This technique involves a stationary phase and a mobile phase. It is generally used for separating compounds based on their adsorption characteristics. However, it is not ideal for compounds that are poorly soluble in organic solvents.
- **Sublimation**: This method is used for substances that can transition from solid to gas without passing through a liquid phase (e.g., camphor, iodine). Since the compound is in an aqueous medium and less soluble in organic solvents, sublimation is not applicable.
- **Continuous Extraction**: This method is specifically designed for extracting compounds from a mixture where the compound is less soluble in the extracting solvent. It allows for the separation of the desired organic compound from the aqueous phase by using a suitable organic solvent in a continuous manner.

3. **Conclusion**:
- Given the properties of the organic compound and the characteristics of the separation methods, continuous extraction is the most effective technique for separating the compound from the aqueous medium.

### Final Answer:
The organic compound is separated by **continuous extraction**.
