**rf and elution**

from a group of samples tested, is it true that the highest rf is the first the be eluted? If so, why is that?

**organic chem, crude mix**

so, the compound with 0.55 rf elutes first? but why is that?

**organic chem, crude mix**

how do i know if the flex column in TLC successfully separated the three crude compounds(which were experimented and had rf values of , 0,0.5 and 0.55) in the crude mixture. Also which compound elutes first? And what is the reason for it to elute first?

**rf factor and compounds**

what does low and high rf factor mean, in compound polarity of its functional groups? Does having a certain kind of functional group increase rf factor, and some decrease? Can someone explain this to me please, with an example. Thank you :)
