Substance a) Draw the best Lewis structure(s), resonances, and structural isomers if any b) In your structure above, indicate polar bonds with dipole arrows toward the more electronegative atom c) Include formal charges if they are not zero Name the electronic around geometry central atom(s) Give hybridization for central atom(s) Name the shape around central atom(s) Show 3-D sketch of the structure and label all bond angles How many sigma bonds? How many pi bonds? Is the substance an ionic compound, a polar molecule, a nonpolar molecule, or a polyatomic ion? C6

Quantum mechanical treatment of valence bond theory refers to the relationship established between the quantum mechanical theory and the valence bond theory to describe the chemical bonding in a particular molecule.
