Problem Paper # 3


November 10, 2003

1. Write possible mechanisms for the following reaction:

[Pt(dien)I]+ + OH- -> [Pt(dien)OH]+ + I-

Which of these mechanisms do you prefer and why?

What are the controlling factors for the rate of this reaction?

2. Propose accepted mechanisms and derive the rate expressions for the following reactions:

(a) [Co(NH3)5Cl]2++ H2O -> [Co(NH3)5OH2]3+ + Cl-

(b) [Co(en)2Cl2]+ + OH- -> [Co(en)2Cl(OH)]+ + Cl-

(c) [Co(NH3)5OH2]3+ + Cl- -> [Co(NH3)5Cl]2+ + H2O


3. Outline the differences between inner and outer sphere electron transfer mechanisms.
