Passage / Comprehension

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.

If "Crystal field splitting energy" $(CFSE = " Δ_{0} ")$ for $[Ti (H_{2} O)_{6}]^{3 +}$ is $242 KJ / mol$ . Find out the magnitude of "Crystal field stabilization energy" (CFSE) in KJ/mol.

Answer:

96.80

Solution:

For $[T i (H_{2} O)_{6}]^{3 +}$ , Ti is in a +3 oxidation state, with a $d^{1}$ configuration. The single electron occupies a $t_{2 g}$ orbital.

CFSE = $0.4 \times Δ_{o} = 0.4 \times 242 K J / m o l = 96.8 K J / m o l$ .
