O O ΟΟ yes no yes no yes hydrogen-bonding force no Between molecules of the compound and molecules of water? O O ОО yes no yes no yes no X 5*Using the expanded structure of C15H11I4NO4 (Levothyroxine), 1. For each central atom in your molecule, decide if it is polar or nonpolar and the decide the type of intermolecular forces it would have (dispersion forces, dipole-dipole, or hydrogen bonds). Color each central atom, based on its type of IMFs (include a key). Make a reasonable prediction stating whether your molecule will be soluble in water or not soluble and explain your reasoning. If your molecule seems to be borderline in polarity, making it difficult to predict solubility, explain your reasoning and the difficulty involved. Find a source (Pubchem, RxList etc.) that discusses the water-solubility of your drug. Compare your predictions with the information you find on the water-solubility of your drug and comment on any discrepancies.
