The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n

Lewis Structure of C\u2082Cl\u2084 (Tetrachloroethene)<\/strong><\/h3>\n\n\n\n

Tetrachloroethene (C\u2082Cl\u2084), also known as perchloroethylene, consists of two carbon (C) atoms and four chlorine (Cl) atoms. The Lewis structure follows these steps:<\/p>\n\n\n\n

    \n
  1. Count the total valence electrons<\/strong>\n
      \n
    • Carbon (C) has 4 valence electrons, and there are 2 C atoms: 4\u00d72=84 \\times 2 = 8.<\/li>\n\n\n\n
    • Chlorine (Cl) has 7 valence electrons, and there are 4 Cl atoms: 7\u00d74=287 \\times 4 = 28.<\/li>\n\n\n\n
    • Total valence electrons<\/strong> = 8+28=368 + 28 = 36.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Determine the skeletal structure<\/strong>\n
        \n
      • Carbon atoms are typically central due to their ability to form multiple bonds.<\/li>\n\n\n\n
      • The two carbon atoms form a double bond (C=C)<\/strong> to satisfy the octet rule.<\/li>\n\n\n\n
      • Each carbon forms two single bonds<\/strong> with two chlorine atoms.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
      • Distribute the electrons<\/strong>\n
          \n
        • The C=C double bond<\/strong> uses 4 electrons (2 per bond).<\/li>\n\n\n\n
        • Each C-Cl single bond<\/strong> uses 2 electrons per bond. With 4 Cl atoms, that accounts for 8 electrons.<\/li>\n\n\n\n
        • The remaining electrons go on Cl atoms as lone pairs.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
        • Check the octet rule<\/strong>\n
            \n
          • Each chlorine has 8 valence electrons<\/strong> (1 bonding pair + 3 lone pairs).<\/li>\n\n\n\n
          • Each carbon has 8 valence electrons<\/strong> (1 double bond + 2 single bonds).<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n

            Polarity of C\u2082Cl\u2084<\/strong><\/h3>\n\n\n\n
              \n
            • Symmetry Analysis<\/strong>: The molecular structure is tetrahedral around each carbon<\/strong>, and the C=C bond is linear<\/strong>.<\/li>\n\n\n\n
            • Dipole Moments<\/strong>: Although C-Cl bonds are polar<\/strong>, the symmetry cancels out dipole moments.<\/li>\n\n\n\n
            • Overall Polarity<\/strong>: Nonpolar<\/strong>, because the symmetrical shape causes the dipoles to cancel.<\/li>\n<\/ul>\n\n\n\n

              Final Answer<\/strong><\/h3>\n\n\n\n

              C\u2082Cl\u2084 is a nonpolar molecule due to its symmetrical shape, even though it contains polar C-Cl bonds.<\/strong><\/p>\n\n\n\n

              Now, I will generate the Lewis structure image.<\/p>\n\n\n\n

              Here is the Lewis structure for C\u2082Cl\u2084 (tetrachloroethene). You can see the two carbon atoms connected by a double bond, each bonded to two chlorine atoms. The lone pairs on chlorine are also displayed. Let me know if you need any modifications or further explanations!<\/p>\n\n\n\n
