Suppose that the TLC plate depicted below was prepared by a researcher who was interested in identifying the composition of an unknown sample. The researcher had reason to believe that the unknown sample might contain either compound A or compound B.
Lane 4 (the co-spot) in the TLC sketch above was left blank. Draw a copy of the TLC plate and predict what lane 4 should look like (add spots to your drawing).
Which compound(s) (A or B or both) are components of the sample of unknown composition?
What is the minimum number of components present in the sample of unknown composition?
Is it possible there are more components than this? Which compound (A or B) is more polar?
