Question

Two cars full of people took a day trip. Car A had a lot of little kids and stopped at lots of rest stops and gas stations to give them a break. Car B had just adults in it, and only stopped once. Of course Car B got to the destination first. Explain how this in an analogy for the paper chromatography you are doing in this experiment.

Answer 1

Explanation:

Considering the problem to be an analogy, we can say that the kids are compared to be more polar or smaller molecular weight compounds. The more polar compounds interact with silica more just as the kids bus stopped at every point and reached the destination late. Whereas, the adult bus is compared to be less polar compounds or high molecular weight which interacts less and reaches the destination faster.

Thus more polar compounds reaches the destination late whereas less polar compound reaches first.
