- Please help me calculate the theoretical yield of [Ru(phen)3)][PF6]2 as seen in the procedure below!In a few sentences summarize your results for odor, solubility, acidity and the FeCl3 test for the knowns. Ethanol 2-Propanol t-Butanol Cyclohexanol PhenolBriefly explain how you determined when the reaction was complete PROCEDURETo 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…
