You used a mobile phase of 90% ethyl acetate (CH3CH2COOCH3)/5% acetic acid (CH3CO2H) as the mobile phase to develop the TLC plate that was spotted with analgesic compounds. What would have been the appearance of the developed plate if a mixture of 80% ethyl acetate and 20% acetic acid were used as the mobile phase? O The order of elution of the compounds would be reversed. O All the compounds would not have traveled as far up the plate. O All the compounds would have traveled farther up the plate. O Some of the compouunds would have migrated farther and some would not have migrated as far.

IN GC, What effect does changing from a temperature ramp to an isothermal temperature program have on resolution of peaks at the beginning of the chromatogram versus the end of the chromatogram. Consider molecular weight and boiling point of the analytes.
Polarities of analyte functional group increase in the order of hydrocarbon < ethers < esters < ketones < aldehydes < amides < amines < alcohols Arrange the order of elution [from shortest to longest retention time] for the following six compounds from an HPLC C18 column. C2H5OH CH3COCH3 CH3COOH CH3COOC2H5 C2H50C2H5 (СН3)2NH O A. C2H5OH < CH3COOH < (CH3)2NH < CH3COCH3 < CH3COOC2H5
In an experiment of Reverse Phase chromatography using C-18 stationary phase and a mixture of methanol/ethyl acetate/acetic acid, a researcher tried to separate the 3 compounds shown below. Which compound would have the lowest Rf and which the highest Rf in this experiment? Explain your answer and show any relevant structures.
An analgesic drug sample was analyzed using TLC to determine its probable active ingredient. The compound may contain compound A, compound B, compound C, or compound D. Five spots were made on the TLC plate, of which four are for the standard compounds (A, B, C and D) and one for the test sample. The solvent was then allowed to pass through the TLC plate. The calculated Rf values of compound A, compound B, compound C, compound D, and the drug sample were 0.24, 0.61, 0.40, 0.89, 0.38, respectively. a. What could be the active ingredient in the analgesic drug sample? Why?
A mixture of three compounds was chromatographed using a silica gel column with diethyl ether/hexanes (10:90) as the eluting solvent. Fractions were collected and TLC analysis of each fraction was performed, with the results shown here: A 3 4 7 8 Mixture before separation Which fractions should be combined to give pure samples of A, B and C?
A chemist was able to extract a biologically active compound and wants to purify the sample since he is sure that the sample still contains impurities. After running the extract in TLC, the chemist found out that the sample produced only one spot near the solvent front. Suggest how the chemist can achieve a better resolution for the chromatogram.

Suppose your TLC plate looks like the image below (ran 1:1 ratio ethyl acetate/hexane). What is the Rf value of the red compound (lower compound, 1 cm from the baseline)? How could the solvent combination be varied to lower the Rf value of the red product? How can we change the eluent composition to improve the separation of the two products on column chromatography? Solvent line 6.8 cm 5.1 cm -* --X- -× - Base line SM Co P rf value choices: 0.1, 0.15, 0.25, 0.3, 0.35, 1.15 how could solvent combination be varied choices: increase ratio of hexane or decrease ratio of hexane how can we change eluent composition choices: start with more polar eluent or start with less polar eluent
A thin-layer chromatography (TLC) experiement was run using three compunds: benzophenone, benzhydrol, and biphenyl. The three solvents that were used with the three compounds were hexane, ethyl acetate, and dichloromethane. Which solvent would be the best for separating these compounds and why?
In TLC, why does the developing solvent 3:1:1 n-butanol/acetic acid/water climb up the TLC plate so slowly?
