Which dorbital configuration has the highest crystal field stabilization energy (CFSE) in a low spin octahedral crystal field? d4 d3 d6 ОООО g8 d? Predic whether the following complex is diamagnetic or paramagentic. 72+ paramagnetic need more information to answer this question diamagnetic The magnetic property of a transition metal complex can be predicted using crystal field theory. If we assume that the magnetic moment arises entirely from unpaired electron spins then the "spin only magnetic moment (us) is given...

Crystal Field Question.
I understand that octahedral shapes have larger splitting energies
then in tetrahedral complexes. And it would take more energy to
split more electrons. So would the order be from Highest to Lowest:
B>A>C where A, B, C are the compounds listed in their
respective orders.
Between Ni(H20)s2+ ; Ni(en)32+; and lowest and why? Cu(CN)42- which has highest splitting and which has
Question 1: Consider the complex ion [Mn(OH2)6] with 5 unpaired electrons. Which response includes all the following statements that are true, and no false statements? I. It is diamagnetic. II. It is a low spin complex III. The metal ion is a d ion IV. The ligands are weak field ligands V. It is octahedral (a) I, II (b) II, IV, V (c) I, IV (d) II, V (е) Ш, IV
a. Predict the structure of [Cr(OH2)6]2+ - I wrote that the complex will undergo Jahn-Teller distortion, making the octahedral complex become tetragonal (don't know if that's correct) b. Account for the variation in the lattice enthalpy of Mn (2780 kJ/mol), Fe (2926 kJ/mol), Co (2976 kJ/mol), Ni (3060 kJ/mol), and Zn (2985 kJ/mol) flouride given that the metal center in all of the flourides is surrounded by an octahedral array of F-ions. c. Explain the effect on the d-orbital energies...
3. [Ti(H20)6]3+ is 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 (tzg and eg) and each of the d-orbitals. d. A. is 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 tz, to the eg orbital. f. What color of the...
Hello. Based on the textbook below I solved a true or false problem. textbook: 1. Light absorption: Sunlight absorbs in the battery 2. Charge generation: Free electrons and holes are generated inside the cell by the absorbed light. 3 Charge Separation: Free electrons and holes are separated by an electric field created at the p-n junction. 4. Charge collection: free electrons move toward n-type semiconductor and holes move toward p-type semiconductor Problem: In solar cells made of organic semiconductors, electron-hole...
