Please draw

-Page: 8 nsition metal ions have high-spin aqua complexes except one: [Co(HO)₁]". What is the d-configuration, oxidation state of the metal in [Co(H:O))"? Name and draw the geometry of [Co(H2O)]? b) Draw energy diagrams showing the splitting of the five d orbitals of Co for the two possible electron configurations of [Co(H2O)]: Knowing that A = 16 750 cm and Пl. = 21 000 cm, calculate the configuration energy (.e., balance or ligand-field stabilization energy and pairing energy) for both low spin and high spin configurations of [Co(H2O)]. Which configuration seems more stable at this point of the analysis? (Note that 349.76 cm = 1 kJ/mol) Exchange energy (IT) was not taken into account in part (d), but it plays a role. Assuming exchange an occur within t29 and within eg (but not between tz, and ea), how many exchanges are possible in the low in configuration vs in the high spin configuration? What can you say about the importance of exchange energy 07
