Consider a sample that is a mixture composed of biphenyl, benzoic acid, and benzyl alcohol. The sample is spotted on a TLC plate and developed in a CH2C12-cyclohexane solvent mixture. Predict the relative Rf values for the three components in the sample. Would biphenyl be closest to the blotted line, then benzyl alcohol, then benzoic acid because these others are increasing in polarity to the non-polar solvent? Thanks!
There were 2 spots on the TLC that did not match up with any of the standards. What were the Rf values of these spots? Identify what these chemical species might be and draw their structures. Solvent was 3:1:1 n-butanol/acetic acid/water. First plate is TLC plate 1. Second plate is TLC plate 2.
1. a compound has an Rf value of 0.97 diethyl ether but an Rf value of 0.045 in cyclohexane. Suggest a couple (at least three) solvent (solvents), or solvent system (systems), that might be better suited for this particular compound. 2. suppose your TLC plate shows only one spot at an Rf value of 0.015 (essentially it does not move). Does this mean that your sample is 100% pure? Explain your answer. 3. suppose your TLC plate shows only one spot at an Rf value of 0.98 (essentially with the solvent front). Does this mean that your sample is 100% pure? Explain your answer.
A student spots an unknown sample on a TLC plate and develops it in dichloromethane solvent. Only one spot, for which the Rf value is 0.95, is observed. Does this indicate that the unknown material is a pure compound? What can be done to verify the purity of the sample?
Using thin-layer chromatography showed that the black dye used in a brand of writing ink contained blue, red, orange and yellow components. The Rf values of these substances using ethanol as the solvent are 0.63, 0.37, 0.79 and 0.16, respectively. How far apart would the blue and yellow components be after the solvent front had moved 7.5 cm from the origin?
A line was drawn 1 cm from the bottom of the TLC plate. The distance the dye spot moved on a TLC plate was 4.5 cm from the line and the distance the solvent moved was 6 cm from the line. What is the Rf value?
Based on the following Rf values from TLC, explain the similarities and differences between Crude 1 & 2. Why is it important to compare the crudes with standard compounds?
The Rf calculated for the TLC separation of a component of two-component mixture is determined to be equal to 2.3. Does this represent good separation or not? Explain.
Identify the statement that correctly interprets this TLC analysis of a recrystallized sample of acetaminophen produced following the procedure outlined in Experiment 5: The TLC of an individuals purified acetaminophen showed two spots. One spot had an Rf identical to that of pure acetaminophen. This spot was also larger and darker than the second spot. The Rf of the second spot was very close to the Rf of pure 4-aminophenol. a) The two spots evident in my TLC analysis indicate my sample is a mixture. Since each spot has an Rf value that is close to the Rf of one of the authentic materials tested, I can conclude my sample is a mixture of acetaminophen and 4-aminophenol. The large size of the spot with an Rf nearly identical to authentic acetaminophen indicates my sample is mostly 4-aminophenol. b)I can conclude from this evidence that my sample is a mixture of acetaminophen and 4-aminophenol because the Rf of each of the spots is nearly identical to one of the authentic…
As1...If a TLC plate shows only one spot with an Rf value of 0.98, does this mean the sample is pure? Briefly explain why or why not.
A student spots an unknown sample on a TLC plate and develops it in pentane solvent. Only one spot, for which the Rf value is 0.05, is observed. Is the un-known material a pure compound? What can be done to verify the purity of the sample?
True or False: Rf values can be used to identify pure compounds, provided that the analysis of the unknown is run simultaneously with the known compound in the same TLC plate.
