Compare the bonding in formic acid (HCOOH) with that in its conjugate base formate ion (HCOO). Each molecule has a central carbon atom bonded to the two oxygen atoms and to a hydrogen atom. Draw Lewis diagrams, determine the steric numbers and hybridization of the central carbon atom, and give the molecular geometries. How do the orbitals differ in formic acid and the formate molecular ion? The bond lengths of the CO bonds in HCOOH are 1.23 (for the bond to the lone oxygen) and 1.36 (for the bond to the oxygen with a hydrogen atom attached). In what range of lengths do you predict the CO bond length in the formate ion to lie?
Answer the following questions for 1,3,5- hexatriene, the conjugated triene containing six carbons. Which MOs are the frontier molecular orbitals?
4. Octatetraene, C8H10, is an 8-membered linear carbon chain with alternating single and double bonds. As a result, each carbon is left with an unhybridized p-orbital containing one electron. This problem will take you through steps to construct and fill the molecular orbital diagram for octatetraene based on the way these different p-orbitals can come together. a) The various molecular orbitals formed from octatetraene’s 8 unhybridized p-orbitals are shown on the next page. Draw the nodal planes for each molecular orbital. Hint: A nodal plane is a line through the molecule that denotes the sites of destructive interference. An example is shown below with ethylene. b) Based on the nodal planes, arrange the energy levels corresponding to the 8 molecular orbitals on the energy level diagram (label them using the numbering provided on the left side of the molecular orbitals) on the next page, in order of lowest to highest energy. c) Populate your molecular…

. The pyridine molecule (C3H;N) is obtained by replacing one C-H group in benzene with a nitrogen atom. Because nitrogen is more electronegative than the C-H group, orbitals with electron density on nitrogen are lower in energy. How do you expect the MOs and energy levels of pyridine to differ from those of benzene?
