Identify the LUMO in the MO diagram of O₂ (shown below). torp +₂² . Пр # Пр #T #% #%₂ s * A) o (2s orbitals) B) o (2pz orbitals) C) TT (2px and 2py) D) TT* (2px and 2py) E) o* (2pz)

Q3) What are the orbital hybridization for each of the following: Explain 1- ВС 2- C,H, 3- Cr(CO), 4- Fe(CO), 5- CH, 6- PtBr,

4. Amphotericin B is a polyene antifungal agent. In the molecule, 6 C-C single bonds and 7 C=C double bonds alternate along a chain of 14 C atoms; see a schematic of the structure of the molecule below. OH OH HO O OH OH OH OH O,,.. OH HO" ОН OH NH₂ Each C atom contributes 1 p electron to the 77 orbitals in the conjugated system giving 14 electrons that move along the molecule. Assuming an average inter-nuclear distance of 140 pm, and that, in the ground state of amphotericin B, each quantum state is occupied by two electrons, use the particle-in-a-box model to calculate (a) the energy separation between the highest occupied state and the lowest unoccupied state, and (b) the frequency of the radiation required to produce a transition between the two states.

1. Draw the MO diagram for HBr. The orbital potential energies for the 4s and 4p of Br are -18.65 ev and -12.49ev, respectively. Recall that the H 1s is -13.61ev.

Indicate the symmetry of the following orbitals: a) Fluorine px orbitals of OF2. b) Fluorine pz orbitals of BF3. c) Oxygen px, Py, and pz orbitals of the CO2 d) Gold s, p, and d orbitals of the[AuCl4]- anion (square-planar structure).

Examine the elements in the second row of the periodictable. Note that HF, H2O, NH3, and CH4all are sp3 hybridized. The first three are all capable of hydrogen bonding.Methane, on the other hand, is not capable of hydrogenbonding. Explain.

Please sketch the лp molecular orbital for CO.

Using specific examples of a homonuclear and heteronuclear diatomic molecule, highlight the differences in their MO energy level diagrams

what is the molecular orbital diagram of AlP? scale it to show splitting and all co tributions to MO from the AO. Draw MO modes for each MO formed. can this exist in the real world?
