Question

Arrange following in order of increasing Rf factor with TLC withsilica or alumina stationary phase: Acetic Acid, Acetaldehyde,2-octanone, decane, and 1-butanol.
Any help would be appreciated!! All answers will be givenpoints!

Explanation / Answer

Acid > Alcohol > Ketone ~ Aldehyde >Alkane the polarity of the functional groups is as shown above from mostpolar acid to least polar alkene, so alkene will be weakly boundedby the stationary phase and will have high Rf value followed byketone followed by aldehyde followed by alcohol followed byacid. hope this helps
