Briefly describe the metal - carbonyl bond using the Dewar - Chatt - Duncanson model. Illustrate your answer with suitable diagrams. Show each bonding component separately and orbital phases must be clearly indicated.

Both water and toluene (C6H5CH3) belong to the C2v point group.  Water has 3 normal modes of vibration, while toluene has 39 normal modes of vibration.  All three of water’s normal modes appear in the IR spectrum of water, while only about 12 of toluene’s normal modes appear in its IR spectrum.  Give two reasons that could explain why all of water’s vibrations appear in the IR spectrum but only some of toluene’s vibrations appear.

Formulate the MO structure of (NO;) for localized o bonds and de-localized 7 bonds. Is it linear or nonlin- ear? Do you expect it to be paramagnetic? Repeat the analysis for NO2 and for NO,.

Sketch a MO energy level diagram for cluster bonding in E6 in Oh Point group using these orbitals ( A1g, t2g, t1u) and populate it with electrons to give maximum bonding character.If E = a Group 13 element with all valence electrons available for cluster bonding, what would be the charge on the cluster to maximise the bonding interactions?

4. The following phosphorous halide molecules contain P as the central atom. i. Draw the expected molecular shape, determine whether it is polar, and indicate the overall direction of the dipole moment. (You do NOT need to show resonance or formal charges AND if there are more than one isomer, please pick one for your answer ii. List all its symmetry elements and show all unique symmetry elements that are not the identity operator or an improper rotation. iii. Determine its point group. а. POCI3 b. РОCІBrz С. РOСІBrl
