Question

Methods used for purification of organic compounds are based on :

• A. neither on nature of compound nor on the impurity present.
• B. nature of compound only.
• C. nature of compound and presence of impurity.
• D. presence of impurity only.

Answer 1

Answer: (C)

nature of compound and presence of impurity.

Answer 2

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).
