Ferrocene, [Fe(Coro)(s):molar mass 186.03 g/moljcan be prepared by reacting 3.0 s of FeCl3(s) (molar mass -126.75 g/mol) with 2.0 g of cyclopentadiene X [CsHol;molar mass 66.01 g/moljand an excess of KOH, as shown in the following reaction FeCl2 + 2CsH6 + 2KOH - FC Ho + 2H2O A student who carried out this reaction obtained 2.7 g of ferrocene. Of the following ?choices which has three correct answers is limiting: 0.0151 g of ferrocene could be theoretically formed; CH () obtained 74.8 % yield is limiting; 2.82 g of ferrocene could be theoretically formed; CH. obtained 95.7 % yield B) is limiting; 4.2 g of ferrocene could be theoretically formed; CH. obtained 54.6 % yield
