Question
In column chromatography, which type of compound elutes first when using a nonpolar solvent (e.g., hexane) on a silica gel column?
Correct Answer
Option B is the correct answer.
Detailed Explanation
On a polar stationary phase (silica gel), nonpolar compounds have less affinity for the stationary phase and elute first with a nonpolar solvent. Polar compounds are retained longer.
Hint
Like elutes with like; nonpolar elutes first.
