The crystal field theory (CFT) is an electrostatic model which considers the metal-ligand bond to be ionic arising purely from electrostatic interaction between the metal ion and the ligand. Ligands are treated as point charges in case of anions or dipoles in base of neutral molecules.
The total number of electrons in orbital of sodium nitropruside i.e. and total number of electrons in orbital of brown ring comcplex i.e. then find value of
Answer:
Solution:
Find (Sodium Nitroprusside): In Na₂[Fe(CN)₅NO], Iron is in the oxidation state (d⁶) with strong-field ligands, causing low-spin pairing: , so .
Find (Brown Ring Complex): In [Fe(H₂O)₅NO]²⁺, Iron exists as Fe⁺ (d⁷) with high-spin configuration due to weak-field water ligands: , so .
Calculate the final value: Substituting the values into the formula gives .
