D)molecular weights

Question

Quizplus · Accepted Answer

The principle of like retains like in gas chromatography refers to the similarity of polarities between the stationary phase and analyte. This means that compounds with similar polarities to the stationary phase will be retained longer and elute later, while those with different polarities will elute earlier. Boiling points, flash points, and molecular weights can also play a role in separation, but they are not the primary factor that governs the retention time of the analyte.
