Question

Separation of organic compounds by column chromatography is due to:

• A. Selective absorption
• B. Selective adsorption
• C. Both absorption and adsorption
• D. Solubilities

Answer 1

The correct option is B Selective adsorption

Column chromatography is a technique which is used to separate a single chemical compound form a mixture dissolved in a fluid. it separates substances based on differenital adsorption of compounds to the adsorbent as the compounds move through the column at different which allow them to get separated in fractions. Hence separation of organic compounds by column chromatography is due to selective adsorption.
