question 188

Essay

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.What is the limiting reagent in this procedure?
B.Based on your answer to part A, what mass of Fe(C₅H₅)₂ could theoretically be formed?
C.A student who carried out this reaction obtained 2.7 g of ferrocene.What was the percent yield for this reaction?
