Question 20 Ferrocene [Fe( CHXsmolar mass 186.03 mol can be prepared tyen 30 s of Fachs) molar mass = 126.75 mol with 20 g of cyclopentadiene (Cs Haco molar mass 66.01 g/moljand an excess of KOH, as shown in the following reaction FeCl + 2CHE + 2KOHFeC1Hio + 2H2O A student who carried out this reaction obtained 2.7 g of ferrocene of the following choices which has three correct answers? CH. Is limiting: 2.82 g of ferrocene could be theoretically formed; obtained 95.7% yield B C.H. is limiting: 4.2 g of ferrocene could be theoretically formed, obtained 54.6 % yield C.H. is limiting: 0.0151 g of ferrocene could be theoretically formed; obtained 74,8% yield O FeCl, is limiting: 4.2 g of ferrocene could be theoretically formed; obtained 89.4 % yield Last saved 12:14:16 Save and 77 minutes remaining
