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.

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°.…
URGENT HELP PLEASE (this is not an exam question) 1-Bromobutane was hydrolysed by an aqueous sodium hydroxide (NaOH) solution. CH3CH2CH2CH2Br + NaOH → CH3CH2CH2CH2OH + NaCl 1-Bromobutane Butan-1-ol During the reaction, the reactant sodium hydroxide is used up. Samples of the reaction mixture were drawn off at regular time intervals and analysed by titration with standard sulfuric acid to find out the concentration of sodium hydroxide. The results are given in the table below: Time / s Concentration of OH- / mol dm-3 0 0.500 100 0.350 200 0.250 300 0.180 400 0.125 500 0.090 600 0.063 700 0.040 800 0.030 Plot a ‘concentration of OH- (mol dm-3) against time (s)’ graph using the results given in the table above.

Grignard reaction: Explain in detail the percent yield and theoretical yield for the following: - initial mass bromobenzene: 7.53g - initial mass magnesium turnings: 1.06g - initial mass methyl benzoate: 2.44g - crude mass triphenylmethanol: 5.43g How can you find pure triphenylmethanol from the crude mixture obtained?
TLC, a powerful analytical tool, can be used to monitor the progress of reactions. The synthesis of ethyl-3-coumarincarboxylate can be monitored by TLC by displaying the starting aldehyde 1, and coumarin product 2, which have very distinct Rf values (Hint: Think about the polarity of compounds 1 and 2 in terms of their abilities to H-bonds to silica gel). What can be determine about the progress of the reaction from analysis of the TLC shown below?

Procedure to complete a Pechmann condensation: Ethyl acetoacetate (7.8 mmol), resorcinol (7.3 mmol) and amberlyst 15 (0.5 g) are mixed in a 25 mL E-flask. In another E-flask, ethanol (15 mL) is added and in a third E-flask water (20 mL). All three E-flasks are heated on a heating plate to approximately 80°C. The reaction mixture is occasionally mixed until the reaction mixture stops bubbling and a gray-white solid is formed. When the reaction is finished, warm ethanol (2 mL) is added to dissolve the solids. The solution is transferred to a clean E-flask using a Pasteur pipette. An additional two portions of warm ethanol (2 mL each) is used to ensure all product is transferred. The solution is warmed up again to ensure all solids are dissolved. To the resulting solution, hot water is portionwise added until the solution starts becoming cloudy. The solution is slowly cooled to room temperature and the precipitate is filtered off and washed with water. (74% yield) Question: Analyze…
