- Can someone explain the answers to 28, 29, and 30? The answers are B, A, A. I understand lindar catalyst makes cis alkenes and Na/NH3 makes trans alkenes but I dont understand how the second step of Br2, OsO4 influences the stereochemistry between the 2 . Will rate quickly if helpful. Thanks!Which compound is not a possible product in the reaction below ( F2 is in excess F2and UV light the catalyst).CHA + F2 -->O CFAO CHFaO CHF-O CH2F2O CHaFSulfate reduction 5C2H4O2 (acetate) + 10H2O = 10CO2(g) + 40e- +40H+ E0’= (-0.28)*(-1) 4SO4- + 40e- + 40H+ = 4H2S(g) + 16H2O E0’= (-0.22) 5C2H4O2 + 4SO4 = 4H2S + 10CO2 + 6H2O full reaction= 0.06 How is 4SO4- + 40e- + 40H+ = 4H2S(g) + 16H2O E0’= (-0.22)? I don't get how it is -0.22 based off the redox tower.
- Describe how the product is purified. 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°. The…(a) Account for the following :(i) Cl – CH2COOH is a stronger acid than CH3COOH.(ii) Carboxylic acids do not give reactions of carbonyl group.(b) Write the chemical equations to illustrate the following name reactions:(i) Rosenmund reduction (ii) Cannizzaro’s reaction(c) Out of CH3CH2 – CO – CH2 – CH3 and CH3CH2 – CH2 – CO – CH3, which gives iodoform test?Why does the final product has the opposite configuration compared to the reactant? Shouldn’t it form OMs first, then OMs gets substituted by Cl- via Sn2 (the 1st inversion of configuration) then the Cl- gets substituted by OCH3- (the 2nd inversion of configuration? To my understanding 2 inversions = same configuration
