Treatment of the bicyclic chloride A with lithium in tetrahydrofuran (THF) gave the monocyclic product B, CoH9Li. In deuterated THF, B exhibited a single proton NMR signal at 6.72 ppm and a single 13C-NMR signal at about 110 ppm. Treatment of B with tetraethylammonium chloride gave a white solid in which N(C2H5)4 replaces Li. Draw a structure for the lithium derivative B. Cl Draw cations and anions in separate sketchers. Separate structures with +signs from the drop-down menu. Treatment of...

Echo 360 Recordings hape homework Untitled [Review Topics] [References] For each of the species below, identify any cyclic conjugated system, then: 1 pts are A. Determine the number of electrons in a system of cyclic conjugation (zero if no cyclic conjugation). B. Specify whether the species is "a"-aromatic, "aa"-anti-aromatic, or "na"-non-aromatic (neither aromatic nor anti- aromatic) (Presume rings to be planar unless structure obviously prevents planarity. If there is more than one conjugated ring, count electrons in the largest.) 1...

Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
