II. Lipids from an organic sample are extracted separately by column chromatography using the ff eluants: 1st eluant - chloroform: methanol: water (6:3:1) 2nd eluant - methanol: chloroform (9:1)3rd eluant – petroleum ether: ethyl ether (1:1) Test results for each eluate are tabulated below. Identify the possible lipid present in each eluate. Based on the results above, _________________ 1. _________________ 2. _________________ 3. _________________ 4. _________________ 5. answer the following questions: What visible positive result for test reagent no. 5?Give the name of chemical characterization test for test reagent no. 3?What class of lipids will give a visible positive result on the test mentioned in question no. 2?Give the chemical name of the product formed after giving a positive result for test reagent no. 1?Test reagent no. 1 is used to test for what organic compound?
