JEE Main 2020 (03 Sep Shift 1)

Question

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

Correct answer
D97

Step-by-step explanation

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
