- Use the following Lewis diagram for methyl acetate to answer the questions: H. :0: H. H- 1. C- - H. Remember that geometry refers to the geometry defined by the atoms, not the electron pairs. The geometry about atom C, is The ideal value of the C-C-O angle at atom C, is degrees. The geometry about atom 03 is1. The electron pair in a H - Cl bond could be considered... a. closer to H because Hydrogen has a larger radius and thus exerts greater control over the shared electron pair b. closer to Cl because Chlorine has a higher electronegativity than Hydrogen c. closer to H because Hydrogen has a lower electronegativity than Chlorine d. an inadequate model since the bond is ionic 2.
