How to calculate theoretical yield benzil in the hexaphenylbenzene experiment, with 0.753 g of benzoin produced.(molecular weight of benzil is 210.28 and amount used 100ml.) Then theoretical yield of tetraphenylcyclopentadienon with 0.264 g of benzil product. (molecular weight of tetraphenylcyclopentadienone is 384.48 and used 100 mg)
In the synthesis of benzil Quinoxaline, I produced 0.38 g, when the reagents were Benzil (0.20 g) and 1,2 phenylendiamine (o.10 g) this is obviuosly impossible due to limiting reagents, but is there any explanation as to why this happened?
4) sketch what a developed and resolved TLC plate of a mixture of benzil, benzoin and hydrobenzoin might look like. Discuss the relative Rf values on your sketched plate 5) In the reduction of benzil with sodium borohydride, 3 compounds are possible: meso-hydrobenzoin, racemic-hydrobenzoin and racemic-benzoin (resulting from incomplete reduction of benzil). Discuss how you determined (or will go about determining) which of these products was produced. Discuss evidence from melting points, TLC and IR spectra.
5. Select the incorrect statement. (2 pts) a) An NMR of of benzoin will have a total integration of 11 b) An NMR of benzil will have a total integration of 10 c) IR spectra of benzoin and benzil are distinguishable from each other d) An IR spectrum of 2,3,4,5-tetraphenylcyclopentadienone is not significantly different from an IR spectrum of benzil. 6. HNO is the (oxidizing/reducing) agent used in the conversion of benzoin into benzil (2 pts) 7. Draw the starting...
