Ans:- The inner sphere electron transfer reaction occurs via formation of a bridged complex. It is explained in the picture below.
4. Predict all possible six-coordinate products for the following inner-sphere electron transfer reactions. Assume that...
(i) Name the two mechanisms by which electron transfer reactions can occur and explain how they differ. (ii)Explain how the following reaction was used to deduce the mechanism of inner sphere electron transfer. [Co(NH3)5Cl]2+ + [Cr(H2O)6]2+ + 5H2O = [Co(H2O)6]2+ + [Cr(H2O)5Cl]2+ + 5NH3
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.
Which of the following is most likely not an outer-sphere electron transfer process? A.[Cu(NH3)5Cl] + [Co(NH3)6]3+ --> [Cu(NH3)5Cl]+ + [Co(NH3)6]2+ B.[Cu(NH3)5Cl] + [Co(NH3)5Cl]2+ --> [Cu(NH3)4Cl2] + [Co(NH3)6]3+ C.[Fe(CN)6]4- + [RhCl6]2- --> [Fe(CN)6]3- + [RhCl6]3- D.[Ni(NH3)5Cl]+ + [Co(NH3)5Cl]2+ --> [Ni(NH3)5Cl]2+ + [Co(NH3)5Cl]+

3. According to the textbook (p. 115). the electron transfer reaction rate between [Co(NH3)]** and (Co(NH3).]?(eq. 5.41) is extremely slow whereas that between [Fe(CN).74 and [Fe(CN).]" (eq. 5.42) is very fast. By using the established facts in the box in answering the following questions. 1. According to the molecular orbital theory, the eg orbitals of an MLO octahedral complex are, in fact, M-L anti-bonding orbitals and the tza orbitals are non-bonding orbitals. 2. According to the spectrochemical series, CN is...
