a) use a less polar solvent.
b) use a more polar solvent
c) develop more quickly (less time to run the separation).
Consider the following errors that could be made when running TLC. Indicate what should be done to correct the error.
a) a two-component mixture containing 1-octene and 1,4-dimethylbenzene gave only one spot with an Rf value of .95. The solvent uses was acetone.
b) a two-component mixture containing a dicarboxylic acid and tricarboxylic acid gave only one spot with an Rf value of .05. The solvent used was hexane.
c) when a TLC plate was developed, the solvent front ran off the top of the plate.
