Q. Which of the following statements is correct?
A) In$\ K_{3}\lbrack Fe(CN)_{6},\$the ligand has satisfied both primary and secondary valencies of ferric ion
B) In $(Cu\left( NH_{3} \right)_{4}SO_{4},$ the ligand has satisfied only the secondary valency of copper
C) In $K_{3}\lbrack Fe(CN)_{6},\$the ligand has satisfied only the secondary valency of ferric ion
D) Both (b) and (c)
Explanation
(c)
In $K_{3}\left\lbrack Fe(CN)_{6} \right\rbrack,$ the ligands are negative which is present in coordination spheres shows a dual behavior. It may satisfied both primary and secondary valencies while, neutral ligand satisfied only secondary valencies
