Co-Ordination Compounds Question 312
Question: In nitroprusside ion, the iron and NO exist as Fe (II) and $ \overset{+}{\mathop{N}},O $ rather than Fe(III) and NO. This can be established by
Options:
A) estimating the concentration of iron
B) estimating the concentration of $ C{N^{-}} $
C) thermally decomposing the compound
D) measuring the solid state magnetic moment
Show Answer
Answer:
Correct Answer: D
Solution:
Fe(II) state - $ 3d^{6} $ ; due to strong $ C{N^{-}} $ ligand spin paired complex $ (d^{2}sp^{3}) $ will be formed.
Hence $ n=0,\mu =OB.M $ Fe(III) state $ 3d^{5};<d^{2}sp^{3} $ complex, n = 1, $ \mu =1.73B.M.$
