BOX 2 BOX 1 Compound(s) dissolved in DCM (in separatory funnel) organic layer 1) 10% aq. HCI (10 mL) 2) 10% aq. HCI (5 mL) aqueous layer Compound(s) at this stage? BOX 4 1) 2) filter, rotovap Compound(s) at this stage? BOX 6 ? BOX 7a filtrate solvent: ? Inorganic compound? BOX 7b BOX 3 Compound(s) at this stage? BOX 5 1) 2) heat, cool, filter isolated material Compound(s) at this stage? BOX 8 ? You have now performed a liquid-liquid extraction protocol in Experiment 4. In doing so, you manipulated and exploited the acid-base chemistry of one or more of the compounds in your mixture to facilitate their separation into different phases. The key to understanding how liquid- liquid extractions work is by knowing which layer a compound is in, and in what protonation state. The following liquid-liquid extraction is different from the one you performed in Experiment 4, but it uses the same type of logic. Your task is to show how to separate apart Compound A and Compound B. Complete the following flowchart of a liquid-liquid extraction. Handwritten work is encouraged. • Draw by hand (neatly) only the appropriate organic compound(s) in the boxes. . Specify the reagent(s)/chemicals (name is fine) and concentration as required in Boxes 4 and 5. Box 7a requires the solvent (name is fine). • • Box 7b requires one inorganic compound. • You can neatly complete this assignment by hand and upload as a PDF. You have access to the following solvents, as needed: • Water • HCI (aq.) • NaOH (aq.) • NaCl (aq.) NH2 Eg loa Compound A Compound B If a solvent concentration is required, use whichever of the following is most appropriate: • 10% (a low concentration) • 4 M (a high concentration) You may wish to refer back to the procedure for Experiment 4 for inspiration. Keep in mind, this liquid-liquid extraction may be similar, but not the same. You may need other chemicals/reagents found in the Experiment 4 materials list that are not included here.
