The correct answer is d. linear, linear<\/strong>.<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

To predict the electron-pair geometry and the molecular geometry of CO2 (carbon dioxide) using VSEPR (Valence Shell Electron Pair Repulsion) theory, we follow these steps:<\/p>\n\n\n\n

    \n
  1. Determine the Lewis structure of CO2<\/strong>:\n
      \n
    • Carbon (C) has 4 valence electrons, and each oxygen (O) atom has 6 valence electrons, for a total of 16 valence electrons in CO2.<\/li>\n\n\n\n
    • The Lewis structure shows a central carbon atom double-bonded to two oxygen atoms, with each oxygen having two lone pairs.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Electron-pair geometry<\/strong>:\n
        \n
      • The central atom, carbon, is surrounded by two regions of electron density (the two double bonds to oxygen). In VSEPR theory, two regions of electron density around a central atom lead to a linear electron-pair geometry<\/strong>.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
      • Molecular geometry<\/strong>:\n
          \n
        • The molecular geometry depends on the arrangement of atoms, not electron pairs. Since there are two atoms (oxygen) bonded to the central atom (carbon) in a straight line, the molecular geometry<\/strong> of CO2 is also linear<\/strong>.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
        • Bond angles<\/strong>:\n
            \n
          • For a linear geometry, the bond angle between the oxygen atoms is 180\u00b0, which is typical for molecules with a linear structure like CO2.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n

            Thus, both the electron-pair geometry and molecular geometry of CO2 are linear<\/strong>, making option (d) the correct choice.<\/p>\n\n\n\n

            In summary:<\/p>\n\n\n\n

              \n
            • Electron-pair geometry<\/strong>: linear (two regions of electron density around carbon).<\/li>\n\n\n\n
            • Molecular geometry<\/strong>: linear (atoms are arranged in a straight line).<\/li>\n<\/ul>\n\n\n\n
