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 5.7 g of cyclopentadiene [C5H6(6;molar mass 66.01 g/molland 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? FeCl, is limiting: 4.40 g of ferrocene could be theoretically formed; obtained 61.36 % yield B C.H. is limiting: 0.0151 g of ferrocene could be theoretically formed; obtained 74.8 % yield C.H. is limiting; 2.82 g of ferrocene could be theoretically formed; obtained 95.7 % yield 6 FeCl, is limiting: 4.2 g of ferrocene could be theoretically formed; obtained 54.6 % yield
