JEE PYQ: Coordination Compounds Question 18
Question 18 - 2020 (03 Sep Shift 1)
The electronic spectrum of $[\text{Ti(H}_2\text{O})_6]^{3+}$ shows a single broad peak with a maximum at 20,300 cm$^{-1}$. The crystal field stabilization energy (CFSE) of the complex ion, in kJ mol$^{-1}$, is: (1 kJ mol$^{-1}$ = 83.7 cm$^{-1}$)
(a) 145.5 (b) 242.5 (c) 83.7 (d) 97
Show Answer
Answer: (d)
Solution
Ti$^{3+} = 3d^1$, $t_{2g}^1 e_g^0$. CFSE $= -0.4 \times 20300 = -8120$ cm$^{-1} = \frac{8120}{83.7} = 97$ kJ/mol.
