Which of the following is true about chromotography? The retention factor is the ratio of the distance the farthest band traveled to the distance the closest band traveled. Beta carotene does not travel far up the paper, because it contains an oxygen group that forms hydrogen bonds with the paper. Analytes with low solubility will migrate a shorter distance than analytes with higher solubility, allowing separation to occur. Different solutes are carried up chromotography paper at different rates, because they are equally soluble.

Analytes with low solubility will migrate a shorter distance than analytes with higher solubility.

Explanation:

Chromatography is a separation method for mixtures in which you need a stationary phase (like the paper) a non stationary phase (the liquid used to separate the mixture).

The compounds of the mixtures that have similar polarity as the non sationary phase will be easily to dissolve, that is the reason that they can travel faster until the end of the chromatography.
