would ethyl acetate/hexane be considered nonpolar or polar overall? I understand that the ethyl acetate is polar and the hexane is nonpolar. Ns am trying to recognize what if polar or nonpolar analgesics would certainly travel further in TLC. I understand that if ethyl acetate/hexane is polar 보다 a an ext polar one will travel further, and if it is nonpolar climate nonpolar will travel further.

I to be looking here and also I check out that caffeine is the many polar (out that aspirin and acetaminophen) and traveled the least distance (lowest $R_mathrmf$) in my experiment. I assumed that ethyl acetate/hexane was polar so ns would have actually thought caffeine would be the least polar due to the fact that it traveled the shortest.

So am ns wrong the ethyl acetate/hexane is polar or space they wrong that caffeine is the many polar?

Never have actually I seen a normal phase (i.e. Silica gelatin or alox) TLC wherein a much more polar compound travels additional than a less polar compound — and also I have actually used some incredibly (considering normal phase TLC) polar eluents in the past.

You are watching: Ethyl acetate polar or nonpolar solvent

The top-running compound are constantly the least polar and also the slowest are constantly the many polar in normal phase TLC.
