1) Do the following for the molecule 1,3,5,7-cyclooctatetraene, shown below (assume it is planar): a) give the hybridization of each carbon b) show the number of electrons in each hybrid orbital prior to bonding and determine which orbitals remain to participate in delocalized bonding; from this, determine the number of electrons that participate in pi-bonding; c) draw a sketch of the sigma-bonding network, d) Using the frost circle method, show the molecular orbital for the delocalized bonding of the molecule; e) Compare, in terms of B, the stabilization gained from this delocalized bonding per carbon-carbon bond to that of ethene, H2CCH2; f) Is this molecule (if planar) aromatic or antiaromatic? How could you have decided this without the molecular orbital? g) Judging from the MO diagram you have drawn, is this paramagnetic? 2) Thinking of diatomics, a) draw the molecular orbital diagram for carbon monoxide, CO. (keep in mind the ‘pi before sigma until after N2’ rule) Also keep in mind the relative energies of O and C, ie,
