for each of the following ions, draw diagrams (on a piece of paper), like the one to the right below, to show orbital occupancies for both weak and strong octahedral fields. indicate (on the table below) the total number of unpaired electrons in each case. ion # unpaired weak field # unpaired strong field 77f74786-b364-4078-95bc-d01001cc8467.gif (a) mn3+ (b) zn2+ (c) cu2+ (d) ru2+ (e) ru3+ part 2: the octahedral complex ion [fecl6]4- has more unpaired spins than the octahedral complex ion [fe(bipy)3]2+. how many unpaired electrons are present in each species? compare the δo values for these complexes. complex ion # unpaired electrons relative δo [fecl6]4- [fe(bipy)3]2+ 2385c317-ba0b-443a-a96a-bfe77d9f77fd.gif
