Question 1
Consider the [Mn(H2O)6]^2+
a) Draw the crystal-field energy level diagram for the 3d obitals and show the placement of d electrons assuming this is a weak-field complex ion.
b) Repeat a) assuming this is a strong - field complex ion.
Question 2
ML6 is a general formula for any octahedral complex ion.
Consider the octahedral complex ion ML6, where M is a transition metal and I is a ligand. If this is a strong-field complex ion, what is the maximum possible number of unpaired electrons in ML6^7. Draw an energy-level diagram with electrons to justify your answer.
