Visualizing spots once the plate is run is crucial in determining the components in the mixture. The above TLC was stained with vanillin in sulfuric acid to visualize the compounds in each essential oil. In our lab, UV will visualize compounds with conjugated double bonds and iodine will stain double bond-containing compounds and some oxygen containing functional groups. Which visualization method would you perform on each of the five molecules above
