Final answer:

In gas chromatography, polar substances will elute more slowly from a non-polar column because they have stronger interactions, contrary to the provided statement which is false.

Step-by-step explanation:

The student has asked whether polar substances will elute out faster from a non-polar column in gas chromatography. This statement is false. In gas chromatography, the principle of "like dissolves like" generally applies, meaning that polar substances have stronger interactions with polar stationary phases, and non-polar substances have stronger interactions with non-polar stationary phases. Thus, in a non-polar column, non-polar substances will elute out quicker, as they have weaker interactions with the non-polar stationary phase compared to polar substances which will interact more strongly and elute more slowly.
