- neither on nature of compound nor on the impurity present.
- nature of compound only.
- nature of compound and presence of impurity.
- presence of impurity only.
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Organic compounds are purified based on:
- The nature of the compound (e.g., solubility, boiling/melting point, volatility, etc.).
- The nature of the impurity present (e.g., soluble or insoluble, volatile or non-volatile, etc.).
Thus, purification methods such as crystallization, distillation, chromatography, and sublimation are chosen based on the combination of the compound’s properties and the impurities involved.
Final Answer is Option (3).
