The spectrochemical series is
I– < Br– < Cl– < F– < OH– < H2O < NH3 < en < NO2– < CN–
Which of the following complexes has the greatest number of unpaired electrons?
Select one:
A. [Fe(CN)6]4–
B. [Ni(CN)6]4–
C. [Mn(CN)6]4–
D. Two of the complexes have an equal number of unpaired electrons that are the greatest number of unpaired electrons.
E. [Co(NH3)6]3+
The correct answer should be "E," but can someone explain why it is?
For the octahedral crystal field diagram discussed in lecture, draw two energy level diagrams of the approximate 3d orbital energy levels. Fill in the first with the correct number of electrons for a high spin Fe (II) system (i.e. [Fe(H2O)62+(aq)], and the second for a low spin Fe (II) system (i.e. [Fe(CN)64-(aq)]).
For the complex ion [Ni(CN)4]2- write the hybridization type, magnetic character and spin nature. [Atomic No.: Ni = 28]
