Question

Column Chromatography Draw the structures in order from least polar to most polar for the following solvents: Acetone, Water, Cyclohexane, Methanol, Methylene chloride, and Hexane. Use the principles of column chromatography to explain why the yellow band passes through the column before the green band. Start by identifying the stationary phase and mobile phase. Explain what would have happened if the acetone-methanol mixture was used first instead of the hexane. Explain what would happen if the

Explanation / Answer

1. order of solvent from least polar to most polar is as follow:

hexane -> cyclohexane -> methylene chloride -> acetone -> methanol -> water

2. using the principle of column chromatography,

yellow band passes through the column before the green band. this is happen because yellow band is less polar as compared to green band or reversily green band is more polar then yellow.

3. if acetone-methanol mixture was used instead of hexane, then since these solvent are highly polar in nature all of the compound pass through column as a mixture.separation of compound will be difficult.
