The relative rate data closely parallel the results obtained in the solvolysis studies. Such a result might be expected from reactions proceeding through similar transition states. The observed order of relative rates may result from better overlap as the size of the central metal atom and the polarizability of its electron shell increase. This would result in increased stabilization and therefore ease of formation of the carbonium ions, proceeding from lighter to heavier metal complexes. 

The ability of transition metals to adopt a number of different oxidation states is a very important feature of transition metal chemistry. In order to determine the oxidation state of a metal in a complex, a simple formalism is adopted where the oxidation state is the charge remaining on the central metal atom when all the ligands are removed in their closed shell configuration . While this...
