Question

explain the splitting of d orbital in [CO(CN)6]3– ion
​

Answer 1

Answer:

The splitting of the d -orbitals into two sets of orbitals in an octahedral [Co(CN6)]3- may be represented as, Here, for d6 ions, three electrons first enter orbitals with parallel spin put the remaining may pay up in t2g orbital giving rise to low spin complex. [Co(CN)6]-3.

Explanation:

As I misused your points in the last question am sorry.
