WHAT FACTORS CAN AFFECT THE YIELD OF BENZOIN CONDENSATION? PROCEDURE To a six inch test tube was added thiamine hydrochloride (0.65 g), followed by water (2mL). The mixture was gently shaken until homogeneous, and then ethanol (7.5 mL)was added. Finally, sodium hydroxide (10%, 1.5 mL) was added and the mixture wasgently stirred to ensure complete mixing.Benzaldehyde (3.8 mL) was then added at room temperature in one portion with gentlestirring. The pH of the resulting reaction mixture was determined and adjusted to >10by dropwise addition of 10% sodium hydroxide. The reaction mixture was then partiallysubmerged in a 65 °C water bath2 and the progress of the reaction was periodicallymonitored by TLC analysis.Once TLC analysis indicated that the reaction was complete, the reaction mixture wascooled to approximately room temperature, and then chilled in an ice-water bath. Theresulting precipitate was collected by vacuum filtration and air-dried. The crude productwas purified by…
Any special precautions or purifications of the reagents required? Limiting and excess reagent? Why is excess necessary? 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…
After a crude product is dissolved in 1.5 mL of hot solvent, the resulting solution is dark brown. Because the pure compound is reported in the literature to be colorless, it is necessary to perform a decolorizing procedure. Should you use pelletized Norit or powdered activated charcoal to decolorize the solution? Explain your answer.

Please type all of the parts to this question occordingly to the instructions. Here is an example of a formal procedure based off of the experiment presented in Mohrig:Sodium hydroxide (4.6 g) was dissolved in water (25 mL). This solution was added to a 100 mL round bottom flask along with methyl salicylate (2.0 mL) and a stir bar. The mixture was heated at reflux for 15 min and then progressively cooled to 5 °C. The solution was acidified with 3M sulfuric acid (15-20 mL), and the resulting solid was collected by vacuum filtration. The crude salicylic acid was recrystallized from water to yield ???? g of final solid. The melting point and IR were taken to assess purity. Calculate the molarity of the solution of sodium hydroxide that is used.a. M = b. If the original procedure is the base scale (100%), how far are we scaling down the reaction when using 0.75 mL of methyl salicylate? (Example: the original uses 2.0 mL, if we were to use 1.0 mL, we would be scaling the reaction down…
