Question

Question 3 (A) The color of the coordination compounds depends on the crystal field splitting energy. Arrange the following complex ions in order of descending order of absorption of wavelength of light in the visible region. [Co(NH3)6]3+, [Co(CN)6]3-, [Co(H2O)6]3+ (B) Usually, tetrahedral complexes are high spin rather than low spin. Explain why. (C) draw the MO diagrams and write the electronic configuration for the complex ion [Fe(NH3)6]3+ and determine the number of unpaired electrons. (D) Explain the nature of bonding in ligand-to-metal charge transfer (LMCT) complex that responsible for the intense purple color of [MnO4]-
