Question 1. Calculate the catalyst loading (in mol %) employed in the following experiment and the TON for the catalyst in the reaction below (note: the balance used is accurate to four decimal places or 0.0001 g = 0.1 mg): [2 pts] Ph Ph PtO₂ cat. EtOAc Ph Ph bibenzyl trans-stilbene "PtO2 (31.5 mg) was weighed into a 100 mL RBF, followed by the careful addition of ethyl acetate (25 mL). trans-Stilbene (1.000 g) was then added to the heterogenous mixture, followed by a magnetic stir-bar. The flask was capped with a pierceable rubber septum... Following complete consumption of the starting material, as determined by GC-MS, the reaction was filtered through a pad of silica and the resulting solution was concentrated to yield 0.9860 g of pure bibenzyl." Here are the molecular weights for all reaction components: PtO2 - 227.08 g/mol; trans-stilbene – 180.25 g/mol; ethyl acetate - 88.11 g/mol; bibenzyl – 182.26 g/mol - mol % = TON =

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…

In a Grignard reaction, 1.4555 g phenyl bromide, 10. g carbon dioxide, 0.5734 g magnesium filings, and 30.2 mL of 6M HCl were used but  only 573 mg of benzoic acid were isolated after recrystallization? what was the percent yield for the overall process?  Give the answer to the nearest whole number please
