In reversed phase partition chromatography Select one: a. the least polar compound elutes first b. the smallest molecular weight compound elutes first c. the most polar compound elutes first d. the largest molecular weight compound elutes first e. the lowest boiling compound elutes first f. the highest boiling compound elutes first

Which one is the more polar component? Explain.

Explain your reasons for choosing which solvent would be most effective in separating the green from blue dye.

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.
