What significant difference would you expect to observe between the UV-vis spectra of (dppe)Mo(CO)4 and (phen)Mo(CO)4 and why?
What significant difference would you expect to observe between the UV-vis spectra of (dppe)Mo(CO)4 and (phen)Mo(CO)4...
The UV/Vis spectra provided are recorded for 0.15 M solutions of Co(II) and Ni(II). Calculate the mass of CoCl2.6H2O which would be dissolved in 250 cm3 of water to produce a 0.15 M solution. Would you expect the mass of NiCl2.6H2O required for the equivalent solution to be significantly different, and why?
Briefly explain what you would expect to see in the UV-visible spectra of the first two compounds you will prepare in this experiment, [Ni(NH3)6][BF4]2 and [Et4N]2[NiCl4]. Which would you expect to give the stronger absorptions, and why?
