Ligand strength = en > ox > F- > I-
Strong field lignad cause large split in energy and due to this it absorb high energy violet , indiogo & blue and their complementary colour observed as yellow , orange & red . So strong field ligand will show lower energy light and weak field ligand will show high energy light. ]
[M(en)3 ] +3 = yellow
M( ox)3] -3 = green
MF6 ] -3 = blue
MI6] -3 = violet

The electronic absorption spectrum UI (Cr(NH3)6]3+ (aq) is shown in Figure 11.5. One of the observed peaks is centered at about 303 nm. 1.a. What is the approximate value of the wavelength for the two other peaks? Which one of these three peaks falls in the visible region of the electromagnetic spectrum? The wavelength at this peak is (Amax), and this transition accounts for the color of the complex ion in solution. The energy of the transition occurring at...

In relation to M(acac)3 complexes, assuming they contain an octahedrally coordinated M3+ ion: Draw the ligand field orbital diagrams for Co(III), Fe(III), Mn(III), and Cr(III) to derive the possible electron configurations for the metal complexes. State the number of unpaired spins each configuration has. Which is the correct d-electron configuration for each complex? Which complexes are "high spin" and which are "low spin"? Thanks so much! I will give immediate upvotes!
