JEE PYQ: Coordination Compounds Question 2
Question 2 - 2021 (16 Mar Shift 2)
$[\text{Ti(H}_2\text{O)}_6]^{3+}$ absorbs light of wavelength 498 nm during a $d$-$d$ transition. The octahedral splitting energy for the above complex is ____ $\times 10^{-19}$ J.
(Round off to the Nearest Integer).
$h = 6.626 \times 10^{-34}$ Js, $c = 3 \times 10^8$ ms$^{-1}$.
Show Answer
Answer: 4
Solution
$\lambda_{\text{absorbed}} = 498$ nm. $\Delta_0 = E = \frac{hc}{\lambda} = \frac{6.626 \times 10^{-34} \times 3 \times 10^8}{498 \times 10^{-9}} = 3.99 \times 10^{-19}$ J $\approx 4.00 \times 10^{-19}$ J.
