Vedclass · Accepted Answer

In ${K_3}[Fe(CN)_6]$,the ligand has satisfied only the secondary valency of ferric ion.

Vedclass · Answer

(A) According to Werner's theory,negative ligands present in the coordination sphere can satisfy both primary and secondary valencies. In ${K_3}[Fe(CN)_6]$,the $CN^-$ ligands satisfy both the primary valency (oxidation state of $Fe$ is $+3$) and the secondary valency (coordination number is $6$). Therefore,statement $(a)$ is incorrect because the ligands satisfy both valencies. Statement $(c)$ is correct because $NH_3$ is a neutral ligand and only satisfies the secondary valency. Since statement $(a)$ is incorrect,the correct choice is $(d)$.
