2. At the end of the extraction lab that you will conduct in a few weeks, you wll repeat this TLC experiment. Your task that day will be to use extraction to separate a mixture of benzoic acid, 2-naphthol, and 1,4-dimethoxybenzene. Explain how TLC could be used to demonstrate successful separation of a mixture into individual compounds.

SEE PHOTO: Effectiveness of separation. Based on the TLC analysis, did the isolated benzoic acidappear pure relative to the starting mixture? Did the isolated naphthalene look pure?How could the purity of the isolated materials be improved?
A student use the same protocol as in the lab manual to extract 4 chloroanilline, benzoic acid and naphthalene. Below are the steps he took Step 1 - Dissolve all three in 15 ml ether and place in separatory funnel Step 2- Add 15 ml of hydrochloric acid and mix well Step 3 - Isolate the aqueous layer and add sodium hydroxide which resulted in a precipitate Step 4- Add 15 ml of sodium carbonate to the ether layer and mix Step 5- Isolate the aqueous layer and add hydrochloric acid, which resulted in a precipitate. Step 6- dry the ether layer and collect the solid that is left
After a complicated chemical synthesis, the last step is to separate two liquids, ACETONE AND ANILINE. What separation method should you use? (Feel free to access the SDS for the two compounds). Be specific about the exact type of separation you choose and explain why.
The question says: what is better: one extraction with a large amount of solvent or 2-3 extractions with smaller volumes of organic solvent? Use evidence from questions 2 and 3 to support your answer. The answers for #2 and #3 are attached as images in this question
1. A student separated the three compounds below using the acid base extraction procedure. He then followed is experiment with TLC using acetone hexanes mixture as mobile phase. What would you expect the student to see on TLC? Would he run into difficulty with the TLC? Explain octahydro-1H-indole Lauric Acid OH NH₂ cyclohexanecarboxamide
You have an aqueous extract that has been dried and you are going to perform a liquid/liquid separation. You must use a mixture of two solvents: a. Which solvent mixture would you use? Available solvents: cyclohexane, chloroform, ethanol, methanol, hexane, acetone. b. What compounds would you expect to be in each phase?
Fully explain what the data in IR and GC-MS spectra mean in the dehydration of 2-Methylcyclohexanol . GC-MS data (gas chromatography): Illustrated in picture *ignore peak at 8.87 minutes Peak 1 mass = 96.2 (1-methylcyclohexene) Peak 2 mass = 96.2 (3-methylcyclohexene) Peak 3 mass = 114.2 (impurity) IR Spectra (Infrared Spectroscopy): Illustrated in picture.
If you ran an unknown sample on a TLC using 3-Methyl-Pentane as eluent and observed only one spot with a Rf value -0.05, is it safe to assume that it is a pure compound? If not, how can you check it out using TLC?
If 80% of a desired compound is extracted into the organic phase in each step (leaving 20% in the aqueous layer), how many extractions are necessary to ensure that at least 99% of the compound has been recovered in the organic phase? 1 extraction 2 extractions 3 extractions 4 extractions
Here is the procedure: Charge a 35 mL microwave reaction vessel with 12 mL of your vegetable oil and 3 mL of methanol (methanol to vegetable oil approximately at a molar ratio of (6 : 1)). Add 0.12 grams of KOH to the mixture. Heat the solution to 85 °C for 5 minutes with stirring. (Note about microwave accelerated synthesis: The reaction is traditionally performed at 65 °C for 30 minutes under reflux in a vessel open to the atmosphere. Question: Explain the rate acceleration observed in the microwave experiment.
Which layer (aqueous or organic) will naphthalene partition into during the extraction process? 3M HCL or Ethyl Acetate
5. Properties and IMF: Chlorophyll a and Chlorophyll b are almost identical in structure, but they separated during TLC. Report the RFs you recorded for both molecules. What functional group(s) are different between them? Then explain these RF values by comparing the IMF present in each molecule to those present in the mobile or stationary phase and how this shaped their affinities for each phase. Use the terms RF, IMF, polar, nonpolar, affinity, mobile phase and stationary phase.
