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.
thanks in advance for all the help... i have been stuck on this question for a while!
