5. Consider valence orbitals of oxygen and those of a transition metal M from Period 4. (a) Complete the reference system and name the d orbital of M and the orbital of 0 overlapped in the T-bond. M= O (b) Sketch the orbitals you named in 5(a), overlapped in the T-bond. Also, sketch the complete reference system. (c) What is the total number of nodal surfaces in the molecular orbital of your sketch?
4. Consider the atomic orbitals of oxygen and a d-metal M. (a) Complete the reference system and name the d orbital of M and the 2p orbital of O overlapping in the o-bond Az M= O (b) Sketch the two overlapping orbitals. (c) What is the total number of nodal surfaces in the overlapping orbitals of your sketch?
How do you determine the number of valence electrons in a transition metal? Also, is the d-orbital or the 4s orbital (for period 4) the outermost orbital?

Please answer for INORGANIC Chemistry!! Thanks!
17. CH2 is isostructural with H2O, thus qualitatively the same MO diagram applies to both (see on the right). On the basis of this consideration, respond to the following: (a) If CH2 had all electrons paired, which of the orbitals would have been the LUMO and the HOMO? (b) Complete the reference system and sketch the HOMO that you indicated above H H (c) Oxidation of CH2 gives formaldehyde H2C=O. Name the atomic orbital...
