The eight diastereomers of 1,2,3,4,5,6-hexachlorocyclohexane has to be drawn and the reason has to be explained for One isomer loses HCl in an E 2 reaction nearly 1000 times more slowly than the others. Concept introduction: Conformations: Rotation about C-C single bonds allows a compound to adopt a variety of possible three-dimensional shapes. Drawing Axial and Equatorial substituents: Each carbon in cyclohexane can bear two substituents. One group is said to occupy an axial position, which is parallel to a vertical axis passing through the center of the ring. the other group is said to occupy an equatorial position, which is positioned approximately along the equator of the ring. E2 elimination: Alkyl halide forms an alkene from the abstraction of the proton from the Î²-carbon atom followed by elimination of the halogen in a single step.

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…
