a Student Who Carried Out This Reaction

question 55

Multiple Choice

Ferrocene, Fe(C₅H₅) ₂(s) , can be prepared by reacting 3.0 g of FeCl₂(s) with an equal mass of cyclopentadiene, C₅H₆(l) , and an excess of KOH, as shown in the following reaction FeCl₂ + 2C₅H₆ + 2KOH $\rarr$ FeC₁₀H₁₀ + 2H₂O
A student who carried out this reaction obtained 2.7 g of ferrocene. Of the following choices which has three correct answers?

• A) C₅H₆ is limiting; 5.2 g of ferrocene could be theoretically formed; obtained 64 % yield
• B) FeCl₂ is limiting; 4.2 g of ferrocene could be theoretically formed; obtained 59 % yield
• C) C₅H₆ is limiting; 4.2 g of ferrocene could be theoretically formed; obtained 54 % yield
• D) C₅H₆ is limiting; 4.2 g of ferrocene could be theoretically formed; obtained 64 % yield
• E) None of the choices have three correct responses
