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

Lewis Structure of Selenium Disulfide (SeS\u2082)<\/strong><\/h3>\n\n\n\n

Step 1: Determine the Total Valence Electrons<\/strong><\/h4>\n\n\n\n
    \n
  • Selenium (Se) is in Group 16 and has 6 valence electrons<\/strong>.<\/li>\n\n\n\n
  • Sulfur (S) is also in Group 16 and each sulfur atom has 6 valence electrons<\/strong>.<\/li>\n\n\n\n
  • Total valence electrons = 6 (Se) + 6 (S) + 6 (S) = 18 electrons<\/strong>.<\/li>\n<\/ul>\n\n\n\n

    Step 2: Determine the Central Atom<\/strong><\/h4>\n\n\n\n
      \n
    • Selenium is less electronegative than sulfur, so Se is the central atom<\/strong>, with the two sulfur atoms surrounding it.<\/li>\n<\/ul>\n\n\n\n

      Step 3: Connect the Atoms with Single Bonds<\/strong><\/h4>\n\n\n\n
        \n
      • We start by forming single bonds between Se and each S. Each single bond contains 2 electrons<\/strong>.<\/li>\n\n\n\n
      • Using 4 electrons for bonds, we have 18 – 4 = 14 electrons<\/strong> remaining.<\/li>\n<\/ul>\n\n\n\n

        Step 4: Distribute Remaining Electrons<\/strong><\/h4>\n\n\n\n
          \n
        • First, we complete the octets of the outer atoms (sulfur atoms).<\/li>\n\n\n\n
        • Each sulfur atom needs 8 electrons in total (including bonding pairs), so we place 6 non-bonding electrons<\/strong> (three lone pairs) on each sulfur.<\/li>\n\n\n\n
        • Now, all 14 electrons are used (6 on each S and 2 in the Se\u2013S bonds).<\/li>\n<\/ul>\n\n\n\n

          Step 5: Check the Central Atom\u2019s Octet<\/strong><\/h4>\n\n\n\n
            \n
          • Selenium has only 4 valence electrons<\/strong> (from the single bonds), which is not a full octet<\/strong>.<\/li>\n\n\n\n
          • To satisfy the octet rule, each sulfur atom shares an extra lone pair with selenium<\/strong>, forming two double bonds (Se=S)<\/strong>.<\/li>\n\n\n\n
          • Now, selenium has 8 valence electrons<\/strong> (two double bonds), fulfilling its octet.<\/li>\n<\/ul>\n\n\n\n

            Final Lewis Structure<\/strong><\/h4>\n\n\n\n
                 :S::    :S:\n      ||      ||\n      Se<\/code><\/pre>\n\n\n\n
              \n
            • Bond Type<\/strong>: Two double bonds (Se=S)<\/strong>.<\/li>\n\n\n\n
            • Lone Pairs<\/strong>: Each S has 2 lone pairs<\/strong>, while Se has no lone pairs<\/strong>.<\/li>\n<\/ul>\n\n\n\n
              Explanation<\/strong><\/h4>\n\n\n\n
                \n
              • Molecular Shape<\/strong>: Linear (AX\u2082 type, 180\u00b0 bond angle)<\/strong> based on VSEPR theory<\/strong>.<\/li>\n\n\n\n
              • Polarity<\/strong>: Nonpolar<\/strong>, since the molecular shape is symmetrical<\/strong> and dipole moments cancel out.<\/li>\n\n\n\n
              • Resonance<\/strong>: No resonance as Se=S bonds are stable.<\/li>\n<\/ul>\n\n\n\n
                This structure satisfies the octet rule<\/strong> and minimizes formal charges<\/strong>, making it the most stable Lewis structure for SeS\u2082<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"
