During an acid base extraction of an organic compound dissolved in dichloromethane with sodium bicarbonate (NaHCO3), you do not recover any of the desired extracted product after completing all the remaining steps. What could the most probable reason(s) be for the observed outcome? -The organic compound you want to extract is also a base; an acid is needed -You did not degassed/vent the separatory funnel -You did not shake the separatory funnel enough to react the base with the organic compound -You did not heat the mixture before the extraction -The organic compound evaporate from separatory funnel during the extraction

For 20.7 the solutions for part c and d dont seem right. Shouldn't reacting with 1 eq of H2 just take away the C=C bond and not the C=O bond. (H2 reduces C=C selectively to form a ketone according to page 738. Also the both the C=C and C=O bond should be reduced if excess H2 is used
The reaction of an organic acid with an alcohol, inorganic solvent, to produce an ester and water is commonlydone in the pharmaceutical industry. This reactionis catalyzed by strong acid (usually H2SO4). A simpleexample is the reaction of acetic acid with ethyl alcoholto produce ethyl acetate and water: CH3COOH(solv) + CH3CH2OH(solv) ⇌ CH3COOCH2CH3(solv) + H2O(solv) where “(solv)” indicates that all reactants and products arein solution but not an aqueous solution. The equilibriumconstant for this reaction at 55 °C is 6.68. A pharmaceuticalchemist makes up 15.0 L of a solution that is initially0.275 M in acetic acid and 3.85 M in ethanol. At equilibrium,how many grams of ethyl acetate are formed?
Provide details about the reaction workup. 4,4'-DIBROMOBIPHENYL [Biphenyl, 4,4'-dibromo-] Submitted by Robert E. Buckles and Norris G. Wheeler1. Checked by R. S. Schreiber, Wm. Bradley Reid, Jr., and Robert W. Jackson. 1. Procedure In a 15-cm. evaporating dish is placed 15.4 g. (0.10 mole) of finely powdered biphenyl (Note 1). The dish is set on a porcelain rack in a 30-cm. desiccator with a 10-cm. evaporating dish under the rack containing 39 g. (12 ml., 0.24 mole) of bromine. The desiccator is closed, but a very small opening is provided for the escape of hydrogen bromide (Note 2). The biphenyl is left in contact with the bromine vapor for 8 hours (or overnight). The orange solid is then removed from the desiccator and allowed to stand in the air under a hood for at least 4 hours (Note 3). At this point, the product weighs about 30 g. and has a melting point in the neighborhood of 152°. The crude 4,4'-dibromobiphenyl is dissolved in 75 ml. of benzene, filtered, and cooled to 15°.…
