These questions consist of two statements each, printed as Assertion and Reason. While answering these questions you are required to choose any one of the following four responses: Assertion: Potassium ferrocyanide is diamagnetic whereas potassium ferricyanide is paramagnetic. Reason: Crystal field splitting in ferrocyanide ion is greater than that of ferricyanide ion.A. If both assertion and reason are true and the reason is the correct explanation of the assertion.B. If both assertion and reason are true but reason is not the correct explanation of the assertion.C. if assertion is true but reason is false.D. If the assertion is false but reason is true

Answer» Correct Answer - C
`K_(4)[Fe(CN)_(6)]` and `K_(3)[Fe(CN)_(6)]` both are low spin complex due to strong ligand field. That is why it is false that crystal field splitting in ferrocyanide ion is greater than ferricyanide ion
