Question

Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: The spin only magnetic moment value for  is 1.74 BM, whereas for  is 5.92 BM.
Reason R: In both complexes, Fe is present in +3 oxidation state.

Strategy:
 Analyze both the magnetic moments (A) and the oxidation states (R) to verify the statements and their explanatory relationship.

Step 1: Evaluate Assertion (A)
- :  ().  is a strong field ligand, forcing a low-spin  configuration  1 unpaired electron. .
- :  ().  is a weak field ligand, keeping a high-spin configuration  5 unpaired electrons. .
(Assertion A is True).

Step 2: Evaluate Reason (R)
In both  and , the central metal is indeed iron in the +3 oxidation state.
(Reason R is Tr
