Question

TI(H20).Jis an octahedral complex. (9 pts) a. Name this complex. b. How many d electrons does it have? c. Sketch the d-orbital diagram for the complex. Label the energy levels tax and e) and each of the d-orbitals. d. Ais 3.99 x 10-19) (per photon). What is the value of A, in kJ/mol? e. Calculate the wavelength of light (nm) needed to excite an electron from the texto the eg orbital. 1 What color of the visible region of the spectrum does this wavelength correlate to? 8. What is this value of A, in wavenumbers (cm)? h. What color would you expect this complex to appear? (Consider the wavelength of light absorbed and whether we see this light). i. Sketch a diagram of this complex.
