The metal's d - orbitals that are directly facing the ligands in K 3 C o C N 6 are:

Options

  1. Ad x y , d x z and d y z
  2. Bd x 2 - y 2 and d z 2
  3. Cd x y and d x 2 - y 2
  4. Dd x z , d y z and d z 2

Correct answer

B. d x 2 - y 2 and d z 2

Step-by-step solution

Give K 3 [ C o C N 6 ] is inner orbital complex with hybridization d 2 s p 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.
