ORGO HOMEWORK #2: A SEPARATION As this nightmare develops, the only way I can eventually grade you is with assignments. Everything will matter, including how responsible you are, how correct you are, etc. You all are way, way more tech savvy than I am, so you can do this if I can do this. Lectures with new material will be coming. For now, this is OLD stuff on which you have NOT been tested. You need to separate the following mixture. (ANSWER WITH LETTERS, STRUCTURES, OR APPROPRIATE WORDS.) This is a SHORTENED version of a separation. That should make it easier. As always, think VERY simple thoughts PLEASE NOTE: SOME OF THE BLANKS DO REQUIRE STRUCTURES, RATHER THAN LETTERS. CH(CH2)2NH, CH(CH2). OH CH (CH)NH,Br a. You add dichloromethine (CHCI) to this mess. You filter the mess. What, if anything, remains? b. Explain your answer to (a). c. You add an equal amount of 10% HCl to the solution. Two layers form. What solvent is on top? d. Explain your answer to (c). What is are in the top layer? What are in the bottom layer? MacBook ERT Yulilol

Answer 1

Solution Given mixture contalns CH₂ CC (2) 2NH2 CH₂ (CH2),204 ₂(CH2)22 NH 3 Br adding CH2Cl2 (BCM) followed by filtration with head to seperation of A 4B from. Therefore ☺ remains seperated. A 4 B are neutral while c ¿ ionic and not soluble in Dcm. adding 10% hice will produce two layers, - w ater is on top © density of Dem is greater than that of water therefore sits down. e when we add uce solution it converts cuz CCH 2), 2 NH2 .. to cuz(CH2)2NH₃ Ce making it soluble inwater. so ® goes in top layer as. (ance) Botrom layer contains 'B' only. water will go off leasing Auce (Cuz (CH2), NH; e) bottom layer will have B after eraposation Yes this is a successful reperation as A, B, and gets seperated.
