I forgot to say how to fix it
a)for a where the solvent is highly polar thus pulling all the solvent with it..I think you can add a solvent of less polarity but rather intermediate polarity
b) I think for this one you can add a solvent with intermediate polarity of course higher than the polarity of hexane.
Consider the following errors that could be made when running the TLC. Indicate what should be done to correct the error.
a) A 2 component mixture containing 1-octene and 1,4- dimethylbenzene gave only 1 spot with and Rf value of 0.95. The solvent used was acetone
b) A 2 component mixture containing a dicarboxilic acid and tricarboxilic acid gave only 2 spot with an Rf value of 0.05. The solvent used was hexane
c) when a TLC plate was developed the solvent ran off the top of the plate.
[b]
a) I think that the compounds are nonpolar while the solvent is polar thus that led to bad seperation. And the solvent was of high polarity.
b) For this one I think that the reason there is bad seperation is that the compounds are polar while the solvent is nonpolar. The solvent has a low polarity thus it doesn't separate well.
c) I think for this one all the person has to do is take out the the plate before the solvent gets that far
Thanks Is my thinking correct?
