When a mixture of three compounds ( is purified by column chromatography using different concentrations of solvents, the following is observed. 1) 50 ml 100 % Hexane-compound 1 elutes 2) 50 ml 20: 80 ether: hexane- compound 2 elutes 3) 100 % ether- compound 3 elutes based on the observations above, choose all the correct statements O compound 3 retains least on the column and is the least polar. O compound 2 is most likely a hydroxyl compound( 2 naphthol) and is somewhat polar O compound 1 retains longest on the column. and is the most polar O compound 1 is most likely a neutral compound (e.g. naphthalene), and is almost non polar O compound 3 is most likely a carboxylic acid like compound ( benzoic acid), and is very polar O compound 2 retains on the column more than 1 but less than 3 because it is a neutral compound.

You run the chromatography system with paper as the stationary phase and 70% isopropanol as the mobile phase. You determine the Rf of a polar analyte to be 0.40. If you use 100% isopropanol (a less polar solvent) instead of isopropanol as the mobile phase what would you expect to happen to the Rf value? No value effect on Rf higher lower could be higher or lower
The surface of the silica gel has a structure that looks like this diagram below.
