[Ti(H2O)6]3+ absorbs light of wavelength 498 nm during a d – d transition. The octahedral splitting energy for the above complex is ______ × 10^-19 J. (Round off to the Nearest Integer) H = 6.626 × 10^-34 Js; c = 3 × 10^8 ms^-1.

1. 1
2. 2
3. 3
4. 4

Correct answer: 3

Solution

The octahedral splitting energy can be calculated using the formula E = hc/λ. Substituting the values for Planck's constant, the speed of light, and the wavelength given, we find that the energy corresponds to approximately 3 × 10^-19 J, which rounds to the nearest integer as 3.
