2. A Tlc plate was run on the fractions (#1-4) collected from a silica gravity column chromatography that was done. The Tlc plate was developed in 20% ethyl acetate/80% hexanes and is shown below. -------- Fraction # 1234 The compounds that were isolated in each fraction are shown below. Label each compound with the number of the fraction that it was likely found in, based on the TLC results. For example, was compound A found in fraction #2? If so, write A = #2 fraction. Do the same for all 4 compounds. CH₂CH₂ .CH3 OH og OH D B CH₂

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 a column chromatography experiment. After purifying compounds by column chromatography, what are two other methods that you can use to confirm the identity of the compounds in each fraction? (other than TLC!) make sure to explain aswell. Thank you
1) When you try separating an unknown mixture by normal-phase liquid chromatography with 50% hexane and 50% methyl t-butyl ether, the peaks are too close together. (not resolved) Should you use a higher or lower concentration of hexane in the next run?
A mixture of biphenyl, benzyl alcohol, and benzoic acid is spotted on a silica gel TLC plate and developed using Ethyl Acetate with 0.5% acetic acid as the solvent. Predict the relative Rf (highest to lowest).
Despite their structural differences, separation of mixtures of organic compounds (such as the arenes benzoic acid, 4-t-butylphenol, and benzamide) often proves difficult. Silica gel chromatography, however, can be used with some success provided that an appropriate solvent is used to provide optimal separation. Consider, for example, the TLC plate pictured at right after developing and UV visualization where prior to elution, lanes A and B were spotted with 4-t-butylphenol and lanes B and C spotted with benzamide. Which of the following must be true? In the space provided, indicate the CORRECT answers (as 1, 2, and/or 3) then explain your reasoning for all three statements. Benzamide elutes faster than t-butylphenol. The Rf for t-butylphenol is less than that of benzamide. Benzamide is more polar than 4-t-butylphenol
Use a suitable model to explain how separation and identification of a mixture of organic compounds can be achieved with a thin layer chromatographic (TLC) technique.
A student used thin layer chromatography to confirm whether he could successfully separate two compounds. Here is the TLC plate he obtained after 30 min. Stationary phase was silica gel and mobile phase was 95 % ethyl acetate and 5 % Hexane mixture.
Two compounds A and B from GC on two open tubular columns contains a XY-1 (100% methyl) and a XY-2 (50% methyl, 50% phenyl), with the same diameter, thickness and length under the same experimental conditions. The retention times and peak widths are show in the Table 1.Hint: phenyl groups interact more strongly with polar groups than methyl groups. Which compound is more polar? Explain your answer
A student places an unknown sample on a thin-layer chromatography plate and develops it in dichloromethane as a solvent. Only one spot whose Rf is 0.98 is observed. Does this result indicate that the unknown material is a pure compound? If not a pure compound, suggest an alternate procedure to verify the purity of the sample.
Which of the following statements regarding size exclusion chromatography is false? Fully included compounds are the last to elute out. Only fully included compounds elute out at Vi. Nothing can elute out before Vo. Only fully excluded compounds elute out at Vo.
Next, 2.00 mL of 9.63 mM S was added to 10.00 mL of a solution of unknown concentration of X, and the mixture was diluted to 25.0mL. Chromatographic analysis of this solution produced peak areas of 4822 for X and 4099 for S. What was the concentration of 5 (in mM) of the 25.0mL solution?
