So i'm a little confused about TLC. I understsand the polar and non-polar aspects of it and all that, but sometimes in questions they will only state that the stationary phase is polar, but never say anything about the mobile phase. So what if the stationary phase and mobile phase are both polar or non-polar? How should I answer if, for example, I'm asked whether a less polar or more polar substance will travel further up a polar TLC plate, but never given the polarity of the mobile phase?
AHHHHHHHHHHHHH Thanks.
AHHHHHHHHHHHHH Thanks.
