The electronic spectrum of TiH2O63+ shows a single broad peak with a maximum at 20,300cm-1.The crystal field stabilization energy (CFSE) of the complex ion, in kJmol-1, is : 1kJmol-1=83.7cm-1
  1. 145.5
  2. 242.5
  3. 83.7
  4. 97

Solution

Ti(H2O)63+ Ti3+=3d1 4s0

t2g1,0,0,eg0,0

CFSE =[-0.4nt2g+0.6neg] 0+n(p)

=[-0.4×1 ]20300

=-812083.7kJ/mole

=-97 kJ/mole
