- The complex ion Fe(CN)63 is paramagnetic with one unpaired electron. The complex ion Fe(SCN)63 has five unpaired electrons. Where does SCN lie in the spectrochemical series relative to CN?arrow_forwardTi(NH3)63+ has a d-orbital electron transition at 399 nm. Find o at this wavelength.arrow_forwardThe solid anhydrous solid CoCl2 is blue in color. Because it readily absorbs water from the air, it is used as a humidity indicator to monitor if equipment (such as a cell phone) has been exposed to excessive levels of moisture. Predict what product is formed by this reaction, and how many unpaired electrons this complex will have.arrow_forward
- 1. Draw all possible electron configurations for octahedral complexes having d" electrons where n=2-9. You will need to draw two spin states for n=4,5,6, and 7 (high spin and low spin configurations). For example, in the case of n=5 one should draw: Low Spin High Spin eg eg 10Dq 10Dq t2g t2garrow_forwardGermanium configuration is its maximum spin multiplicity?
