Is the following statement an accurate description of a factor that contributes to the ordering of the spectrochemical series for ligands and metals?
1) higher oxidation state metals form stronger bonds with ligands
Homework Answers
No, The Reason is not Appropriate. As the Oxidation State of the Metal increases, the Crystal Field Splitting increases due to greater repulsion with the Ligand Orbitals. This is the Basis for Spectrochemical Series of the Metals.

Question 47 1 pts Which of the following is an accurate description of the ability for an element to absorb radiation (electromagnetic waves, e.g. light)? Electrons only absorb and re-emit wavelengths of radiation that have the same energy as the difference between an electron's ground state and excited states Electrons can be excited by any wavelength of radiation but only emit radiation equal to the difference in energy between a ground and excited state Electrons in an atom can only...

consider this six metal ligand , answer the following question. [Ni(NH3)6]Cl2,[Ni(en)3]Cl2.2H2O,[Ni(pn)3]Cl2.2H2O,[Ni(bipy)3]Cl2 and [Ni(phen)3]Cl2 1. Draw the structures of all of the ligands used in this experiment and place them in order of their increasing ligand field strengths. How does this compare with the spectrochemical series for ligands detailed in the literature? 2. Draw structures by hand (using 3D depictions for the metal-ligand bonds) for all of the metal complexes indicating which ones are chiral and which ones are not. 3....
