Using cartoon representations, draw a molecular orbital mixing diagram for a CO bond. In your picture, consider the relative energies of C and O and how this changes the resulting bonding and antibonding molecular orbitals relative to a CC bond.
For each of the following molecules, identify whether it is a valid Lewis structure and if not, explain why. Then, regardless of whether it is a valid structure or not, use VSEPR to identify the expected 3-D structure.
Which of the following statements are TRUE for covalent pi bonds? (Choose as many as apply. Hint: There are 4 correct answers!) Pi bonds arise from head-on overlap of two orbitals. Pi bonds arise from sideways overlap of two orbitals. The electron density in a pi bond is found above and below the axis between the two bonded nuclei. The electron density in a pi bond is found in between the two bonded nuclei. A pi bond can exist independently; not every pi bond is accompanied by an associated o bond. Pi bonds always exist in conjunction with an associated o bond; they can never exist independently. The pi bonds in a molecule determine the shape of the molecule. There can be more than one pi bond between two nuclei. Every covalent bond contains at least one pi bond.
Consider a molecule AB, where element A has 6 valence electrons and B has 7 valence electrons. If the AEn for each bond = 1.2, predict the shape, bond hybridization and polarity (polar or non-polar) of the molecule. Your answer should follow the format: a) number of total electrons for bonding; b) Steric Number and Lone Pairs; c) name of shape based on the VSEPR chart, d) bond hybridization and e) molecular polarity.
Select only individual atoms, and not the bonds between them. Double bonds may be conjugated, meaning that there is one single bond between them. Identify all the atoms in the structure below that must lie in the same plane.
Given the molecule CH2CHCN Please draw a Lewis structure for this compound with CORRECT GEOMETRY and label all sigma and pi bonds with the orbitals it is made from (what orbitals are overlapping to form the bond). You may draw the hybridized sigma orbitals as sticks and the unhybridized p-orbitals as lobes for clarity. For this question, you DO need to draw out the orbitals.
