Micaela A. JaramilloNovember 14, 2016CHEM 121LPartners: Morelia CuevasArzoo RishadMolecular Modeling of Covalent CompoundsPost Lab Questions1.Part of the reasoning that led van’t Hoff and Le Bel to propose a tetrahedral shape for Methane, CH4,wasbased on the number of compounds that are theoretically possible for substituted Methanes, that is, compoundsin which one or more hydrogens have been replaced by some other group. For example, only on compound ofthe type CH2X2has ever been found. Is this consistent with a tetrahedral shape? With a square shape? Providean explanation for each answer using appropriate diagrams.2.For H2O, the H-O-H bond angle is 104.5° and the measure dipole moment is 1.85 Debye. What is themagnitude of the O-H bond dipole moment for H2O? Estimate the bond angle in H2S given that the H-S bonddipole moment is 0.67 Debye and the resultant molecular dipole moment is 0.95 Debye.
