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

Text Solution

Verified by Experts

The correct Answer is:
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
