- In light of your answer to Problem 30-40, explain why a mixture of products occurs in the following reaction: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°.…Make a table of the physical properties (molar mass, MPT, BPT density and mass used/needed) for the reduction of benzophenone lab reactions.

(Ksp, PbF2 = 6.76 x 10-4 and dissociation constant of HF is 3.7 x 10-8)6) During the Wittig reaction, you perform the reaction as follows:4-chlorobenzaldehyde (136 mg) and (carbethoxymethylene)triphenylphosphorane(323 mg) were placed in a 25 mL Erlenmeyer flask. The two solids were mixed vigorously for 15 min. The reaction mixture was diluted with hexanes (2.9 mL - density 0.661 g/mL) The by-product, triphenylphosphine oxide, was filtered off.0.085 g total of triphenyl phosphine was isolated. The filtrate was then evaporated to dryness to obtain 0.151 g of the desired product, pure ethyl-4-chlorocinnamate, as a colorless oil.What is the % effective mass yield of the reaction? (Your result should be reported as a % value and rounded to the nearest integer.
