Question
in looking through some references to experimental procedures, a student finds two references for purifying a compound from a reaction mixture. in one procedure, pure added to the column. happen if the solution (Be sure your is too dilute when it is the order in which the following compounds will elute from a chromatography acid, and looking through some references to experimental procedures, a student finds two references for purifying a compound from a reaction mixture. In one procedure, pure is obtained by carrying out column chromatography using a solvent mixture of and ethyl acetate. In the second procedure, methylene chloride is used as the phase. Assuming the time required and the volumes of solvents are equal, what advantages and disadvantages of each of these solvent systems? CHROMATOGRAPHY AND TLC in Chapter 7, column chromatography and thin la chromatography have much in common. Both are examples of solid-liquid chromatography. Both use an such as alumina or silica for the stationary phase and organic solvents as the phase. In a TLC experiment, compounds are separated as they move up the plate mobile phase. In a column chromatography experiment, compounds will be separated as they travel down a column with the mobile phase. As you will see in procedure, thin layer and column chromatography are often used this procedure. In Chapter 7, TLC was n conjunction with each other in an experimental the active ingredients in commercia rrale to senarate and identifyExplanation / Answer
Following compounds will elute from chromatography column in the order in which you have listed them.
The most polar would elute last.
I think benzoic acid is the most polar.
The least polar would elute first. I wonder if that isn't acetophenone.
