In Part 1 of the experiment, the different colored bands signified the different functional groups present in the unknown compounds. The table below summarizes the colored bands observed in each solvent and their corresponding functional groups:

| Solvent | Colored Band | Functional Group |

|---|---|---|

| Hexanes | Purple | Alkenes |

| Ethyl Acetate | Blue | Ketones |

| Ethanol | Yellow | Aldehydes |

| Water | Orange | Carboxylic Acids |

By observing the colored bands in each solvent, we can tentatively identify the functional groups present in the unknown compounds.
