JEE Advanced Chemistry question

Nitroprusside ion is and not . and can be differentiated by

(A)Estimating the concentration of iron
(B)Measuring the concentration of
(C)Measuring the magnetic momentCorrect
(D)Thermally decomposing the compound

Answer: (C)

Solution

Formulations (, , diamagnetic in the low-spin strong-field environment, since the formal leaves iron with an even, paired configuration) and (, , which would retain at least 1 unpaired electron even in the low-spin case)
