3) The d orbital electron configuration of octahedral complexes can either be described as high- spin with the maximum possible number of unpaired d-electrons, or low-spin containing one or more paired d-electrons. [Fe(H20)62 is a high-spin octahedral complex. What is its spin- state (S-?)? Draw a d-orbital splitting diagram for this complex and fill it with the appropriate number of electrons. Where does the final electron go in this diagram? If you were to oxidize this molecule do you think...
5) Draw d orbital splitting of an octahedral complex. Calculate CFSE for a high spin Fe(II) complex in an octahedral geometry. Calculate spin only magnetic moment for the complex too. 6
1.- Define what are complex ions 2.- Using NiCl as a reactant look in a book or in the web for a reaction to form a complex ion, indicate which is the Lewis acid and which is the Lewis base. An example of your answer is this: Ag (aq) + 2NH, (aq) - Ag(NH),(aq) Lewis acid Lewis base 3.- Using the rules of nomenclature name the complex you have proposed in question 2 4.- Indicate the coordination number and geometry...
3. Based on CFT qualitative discussions in class, qualitatively sketch the energy level diagram for the d orbitals in an Oh field; then fill in the electrons for the metal ion a. Do you expect the complex to be high spin or low spin? Why? b. Do you expect the ion to be paramagnetic or diamagnetic? c. Can magnetism confirm whether the electron configuration as i. Do both high spin and low spin yield the same magnetism Why? high spin...
