In which of the following coordination entities the magnitude of 0(CFSE in octahedral field)will be maximum?
(c) As in all the given complex the central metal atom is same and contains same number of d electrons, thus CFSE is decided by ligands. In case of strong field ligand, CFSE is maximum. CN- is a strong filed ligand,Hencem in [Co(CN)6]3- CFSE is maximum.The magnitude of oct will be maxmimum in [Co(CN)6]3-
