Do polar compounds travel further or less far than unpolar ones in hexane/ethyl acetate TLCs?
Never have I seen a normal phase (i.e. silica gel or alox) TLC where a more polar compounds travels further than a less polar compound — and I have used some extremely (considering normal phase TLC) polar eluents in the past.

The top-running compounds are always the least polar and the slowest are always the most polar in normal phase TLC.
