Question

draw energy level diagram to show the low- and high spin octahedral complexes of the transition-metal ions that have the electron configurations d4 d5 d6 and d7

Explanation / Answer

hi...i have answered this question ... i hope you know what is t2g and eg orbitals ..... d4 ---> low spin = (t2g) ^4 (eg)^0 it means that in low spin state t2g will have 4 e- and eg will have 0 electrons energy = 4 X -0.4 = -1.6 ? d4 --> high spin = (t2g) ^3 (eg)^1 energy = 3 X -0.4 + 1 X 0.6 = -0.6 ? d5 --> low spin = (t2g) ^5 (eg)^0 energy = 5 X -0.4 = -2 ? d5 ---> higgh spin = (t2g) ^3 (eg)^2 energy = 3 X -0.4 + 2 X 0.6 = 0 ? d6 ---> low spin = (t2g) ^6 (eg)^0 energy = 6 X -0.4 = -2.4 ? d6 ---> high spin = (t2g) ^4 (eg)^2 energy = 4 X -0.4 + 2 X 0.6 = -0.4 ? d7 ---> low spin = (t2g) ^6 (eg)^1 energy = 6 X -0.4 + 1 X 0.6 = -1.8 ? d7 ---> high spin = (t2g) ^5 (eg)^2 energy = 5 X -0.4 + 2 X 0.6 = -0.8 ? feel free to ask any question just remember that t2g orbitals are dxy,dyz and dxz orbitals and eg orbitals are d(x^2-y^-2) and dz^2 orbitals
