Question

Sketch d-orbital splitting diagrams for the following complexes (be sure to show clearly the number of unpaired electrons):

a) [Cr(OH₂)₆]³+ , Octahedral

b) [CoCl₄]²- , tetrahedral

c) Pt(NH₃)₂Cl₂, square planar

d) [Rh(CO)₆]³+ , octahedral

Answer 1

D-orbital splitting diagrams depend on the geometry of the complex and the metal's electronic configuration. Octahedral complexes with strong field ligands tend to have fewer unpaired electrons, while tetrahedral complexes often have more unpaired electrons due to weaker field splitting.

Step-by-step explanation:

When drawing d-orbital splitting diagrams for transition metal complexes, the geometrical structure of the complex has a significant impact on the arrangement and energy levels of the metal ion's d-orbitals. Here are the diagrams for the given complexes:
