The most appropriate method for separating a large quantity of a mixture of nonvolatile, nonpolar organic compounds would be__________?
Correct answer: D. Column chromatography
- A. Distillation
- B. Extraction
- C. Gas chromatography
- D. Column chromatography
Explanation
Column chromatography is suitable for separating a large quantity of nonvolatile organic compounds because different compounds adsorb to the stationary phase with different strengths and can be collected in separate fractions. Students may choose gas chromatography because it separates organic compounds efficiently, but it requires volatile, thermally stable substances and is generally used for smaller analytical samples.

About Classification of Organic Compounds
Organic compounds are classified by carbon skeleton into open-chain, branched-chain and cyclic compounds, including homocyclic and heterocyclic types. The classification also uses functional groups to distinguish hydrocarbons, halo compounds, alcohols, aldehydes, ketones, carboxylic acids and their derivatives, which is different from naming compounds by IUPAC rules.
