Which Of The Following Statements Regarding Thin Layer Chromatography Are True?

Thin layer chromatography is an example of adsorption chromatography, and not partition chromatography. In thin layer chromatography, a polar organic compound will be repelled by the adsorbent and therefore travel further up the plate than a non-polar compound. Covering the sample jar is done to prevent fingerprints on the slide. Larger sample spots give better Rf values. In thin layer chromatography, a polar organic compound will be attracted to the adsorbent and therefore travel further up the plate than a non-polar compound The Rf" value for a particular compound is a fixed constant , independent of absorbent material.
