How would a mixture of naphthalene and benzophenone behave on a TLC plate with hexanes /...
How would a mixture of naphthalene and benzophenone behave on a TLC plate with hexanes / acetone as the eluent? Compare the polarity of these two compounds. Outline the most commonly used procedure for the purification of an impure solid material using the technique of recrystallization. Why is acetone such a popular solvent? Point out one drawback in terms of safety considerations. Your final product might be impure since you suspect decomposition might have occurred. When determining the melting point...

What is the literature (known) melting point for acetanilide? A student performed a recrystallization to purify a crude sample from a reaction. The amount of crude material collected from the reaction was 13.56 grams. After the purification, the student collected 8.97 grams of extremely pure material. a. What is the percent recovery of the desired material? b. Is it possible to determine how much of the desired material remained in solution after the filtration? The solubility of acetanilide in hot...

RTY Uno Collect the recrystallized product by vacuum filtration with the clamped Hirsch funnel and wash the crystals with 1 mL of cold, 50% aqueous ethanol. Then allow the crystals to air dry until the next laboratory period. Percent Yield and Characterization Weigh the dry product and calculate a percent yield. Then determine its melting point range and compare the result with the literature value. Submit the product in a labeled plastic bag with the report Questions 1. Use the...
