Question

A student is studying the magnetic and kinetic properties of a transition metal complex as we did in this laboratory experiment. Use the experimental information below to determine the d-electron configuration of the transition metal ion. From kinetic studies, it is determined that the metal center is inert. From this observation, determine which d-electron configurations are possible candidates for our unknown complex. Sort the d-electron configurations below into the appropriate "possible d-electron configurations" From magnetic studies, it is determined that there is one unpaired electron. From this observation, determine which d-electron configurations are possible candidates for our unknown complex. Sort the d-electron configurations below into the appropriate "possible d-electron configurations" and "impossible d-electron configurations" bins. Based upon the experimental observations and the conclusions you made above, what must the d-electron configuration of the complex be?

Explanation / Answer
