The metal \(d-\) orbital that can directly facing the ligands in \(K_3[Co(CN)_6]\) are
- A \(d_{xy}\) and \(d_{x^2 - y^2}\)
- B \(d_{x^2 - y^2}\) and \(d_{z^2}\)
- C \(d_{xz} ,d_{yz}\) and \(d_{z^2}\)
- D \(d_{xy}, d_{xz}\), and \(d_{yz}\)
Answer & Solution
Correct Answer
(B) \(d_{x^2 - y^2}\) and \(d_{z^2}\)
Step-by-step Solution
Detailed explanation
Given \(K_3[Co(CN)_6]\) is inner orbital complex with hybridization \(d^2sp^3\) and octahedral geometry. Ligands are approaching metal along the axes. Hence, \(d_{x^2 - y^2} , d_{z^2}\) orbitals are directly in front of the ligands
