a. explain why we do not worry about low spin complexes in a tetrahedral geometry. (Your answer should be only one sentence.)
Answer: Formation of the low spin complex in the tetrahedral complex is not possible because the energy required for pairing is greater, rather they moved in the high spin state.
b. Use the Irving-Williams series of ligands to predict if an octahedral complex is likely to be high spin or low spin for the following catalytic/transport active sites:
a) in Photosystem II, the Mn(II)-Cl group
b) in hemerythrin, the Fe(III)-O2H- group
a) in Photosystem II, the Mn(II)-Cl group: high spin
b) in hemerythrin, the Fe(III)-O2H- group; high spin
