You have performed the reaction below and decided to purify the crude product using Br KOH, ELOH + KBr + H20 H3CO recrystallization. Below is a TLC plate containing lanes for the starting material, crude sample, recrystallized sample, and filtrate. Was your recrystallization successful? Why or why not? Note the gray spots represent faint spots on the TLC plate. Spot H was identified as the product.

Pls help ASAP. Pls show all work and calculations.
REACTION RECRYSTALLIZATION (OPTIONAL) 1. Begin assembling your reflux apparatus (i.e. lab jack, stir plate, exten- sion clamp and round-bottom flask of appropriate size). 10. Weigh your crude solid to calculate an approximate crude yield. Transfer most of it to a 125 mL erlenmeyer, but keep some aside (~100 mg) for analysis at the end. 2. Add para-aminophenol (15.0 mmol), demineralized water ([para- aminophenol] = 0.75 M) and a stirbar to the flask. Set to stir vigorously. 11. Recrystallize your solid by boiling in an erlenmeyer in a minimal volume of demineralized water (~8 mL/gram of crude solid) on a hot plate to fully dissolve it. If necessary, slowly add water portion-wise until a homogeneous solution is obtained. 3. Measure the required volume of acetic anhydride (1.30 eq.) in a small graduated cylinder. Using a platic pipette, add it to the reaction flask. 4. Finish the assembly of the reflux apparatus (i.e. secured water con- denser along with tubing, heating mantle and…
Plant pigments in spinach were separated with TLC with cellulose as thestationary phase and 80/20 diethyl ether/acetone mixture as themobile phase. If needed, the solvent structures in the lab Appendix.1. Determine the Rf values of each plant component on this TLC plate.2. Arrange the plant components from most polar to most nonpolar. Please answer both 1 and 2 (picture below is the same question attached )
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?
