Pre-Lab QuestionsA food sample contains three unknown color pigments with the codes 0, Y, and G. After a paperchromatography experiment separates the pigments in the food sample, O is calculated to have thehighest Rf value while G has the lowest Rf value.a. Which pigment has the greatest intermolecular interactions with the stationary phase?b. Which pigment has the greatest intermolecular interactions with the mobile phase?1.2. From the experiment in Question 1, the following data were obtained:5.5 cmDistance traveled by spot ODistance traveled by spot YDistance traveled by spot GDistance traveled by solvent front4.0 cm3.0 cm6.0 cmCalculate the retention factor (Rr) for each spot.
