For [Fe(H₂O)₆]²⁺, treated by crystal field theory with water as a weak-field ligand, let X be the number of electrons in t 2 g , Y the spin-only magnetic moment in BM, and Z the number of electrons

Question

For [Fe(H₂O)₆]²⁺, treated by crystal field theory with water as a weak-field ligand, let X be the number of electrons in t 2 g ​ , Y the spin-only magnetic moment in BM, and Z the number of electrons in e g ​ . Find X + Y + Z. Give the answer to two decimal places.

TestHub · Accepted Answer

Fe²⁺ is d⁶ and high spin: t 2 g ​ ⁴ e g ​ ², so X = 4 and Z = 2 with four unpaired electrons. Y = √(4×6) = √24 = 4.90 BM. X + Y + Z = 4 + 4.90 + 2 = 10.90.
