Ferrocene, [Fe(C10H10)(s) ;molar mass 186.03 g/mol]can be prepared by reacting 3.0 g of FeCl2(s) [molar mass =126.75 g/mol] with 2.0 g of cyclopentadiene [C5H6(l); molar mass 66.01 g/mol]and an excess of KOH, as shown in the following reaction FeCl2 + 2C5H6 + 2KOH FeC10H10 + 2H20 A student who carried out this reaction obtained 2.7 g of ferrocene. Of the following choices which has three correct answers? A FeCl, is limiting: 4.2 g of ferrocene could be theoretically formed; obtained 89.4 % yield B CH. is limiting: 4.2 g of ferrocene could be theoretically formed; obtained 54.6 % yield CH is limiting: 0.0151 g of ferrocene could be theoretically formed; obtained 74.8 % yield 6 D C.H. is limiting: 2.82 g of ferrocene could be theoretically formed; obtained 95.7 % yield
