Identify the error in the following scenario and indicate how you would fix the error: A TLC of a two component mixture of pentene and 1,3-diethylbenzene was run in acetone. An Rf value of 0.90 was reported.
I think I got something: there should be 2 Rf values, since there are two components; maybe the spot was not concentrated enough. So the way to fix the error would be to make the spot bigger. Is this right?
