In potassium ferrocyanide, there are ______ pairs of electrons in the t 2 g set of orbitals.

Correct answer

0

Step-by-step solution

Potassium ferrocyanide, K 4 Fe CN 6 , has a central iron ion that is coordinated with six cyanide ligands in an octahedral geometry. The oxidation state of the iron ion in potassium ferrocyanide is + 2 , hence has d 2 sp 3 hybridised state. On applying C . F . T . it shows that all the 6 electrons of d subshell are present in the form of three pairs in t 2 g orbitals. Hence answer is 3 .
