a) Explain how electron transfer takes place between the complexes in oxidation-reduction reactions related to inner-sphere and outer-sphere mechanisms, respectively.
b) You are told that the oxidation-reduction reaction between [Co(NH3)6]^3+ and Ru(NH3)6^2+ takes place via outer sphere electron transfer and the rate constant is 1.1 x 10^–2. However, if instead of Ru(NH3)6^2+, [Cr(bipy)3]^2+ is the reductant then rate constant is much higher, 6.9 x 10^2. Explain the reason.
Homework Answers
Ans:- Outer sphere electron transfer phenomenon depends on the reorganization energy involving solvent, coordination geometry, bond length changes in oxidant and reductant for the process to take place.
It depend on orbital symmetry as described in picture
