Question

The metal d-orbitals that are directly facing the ligands in k3[co(cn)6] are:

Answer 1

Potassium hexacyanocobaltate(III) is a coordination compound and is formed by the cyanide ligand which is a strong field ligand. The metal d-orbitals that are directly facing the ligands in Potassium hexacyanocobaltate(III)- K3[Co(CN)6] are d(x2-y2) and dz2

Answer 2

The metal d-orbitals that are directly facing the molecule in k3[co(cn)6] are d(x2–y2) and dz2.  

Explanation:

• In case of the complex compound k3 [co (cn)6], the shape of the compound is octahedral in nature.

• As a result the position of the orbital is that of an octahedral compound.  

• Hence the two orbitals d(x2–y2) and dz2 are located in an axial location.

• So if we see from the plane of the compound that these orbital directly face the molecule of the compound.  

• The energy which is present in the axial orbital are raised in this process.
