Correct Answer:<\/strong>
\u2705 b) O=S=O<\/strong>
\u2705 c) :O\u2013S\u2013O<\/strong>
\u2705 d) :O\u2013S=O<\/strong> (Assuming a resonance structure was meant here)<\/em><\/p>\n\n\n\n

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

Sulfur dioxide (SO\u2082)<\/strong> is a chemical compound consisting of one sulfur (S) atom and two oxygen (O) atoms. To determine the correct Lewis dot structures<\/strong>, we must consider the valence electrons<\/strong>, octet rule<\/strong>, and formal charges<\/strong> to draw the most accurate representations of bonding.<\/p>\n\n\n\n

Step 1: Count total valence electrons<\/h4>\n\n\n\n
    \n
  • Sulfur (S) has 6 valence electrons.<\/li>\n\n\n\n
  • Oxygen (O) has 6 valence electrons \u00d7 2 = 12.<\/li>\n\n\n\n
  • Total = 18 valence electrons<\/strong><\/li>\n<\/ul>\n\n\n\n

    Step 2: Choose a central atom<\/h4>\n\n\n\n

    Sulfur is less electronegative than oxygen, so it serves as the central atom<\/strong>.<\/p>\n\n\n\n

    Step 3: Arrange atoms<\/h4>\n\n\n\n

    Attach the two oxygen atoms to the sulfur atom with single bonds initially. This uses up 4 electrons (2 bonds \u00d7 2 electrons).<\/p>\n\n\n\n

    Remaining: 18 \u2013 4 = 14 electrons<\/strong> to be placed as lone pairs.<\/p>\n\n\n\n

    Distribute electrons to fulfill the octets of the oxygen atoms and then sulfur. After distributing, we find that formal charges<\/strong> are not optimized. So, we form double bonds<\/strong> between sulfur and one or both oxygens to reduce formal charges and better reflect reality.<\/p>\n\n\n\n

    Resonance Structures of SO\u2082:<\/h4>\n\n\n\n
      \n
    1. O=S\u2013O\u207b<\/strong><\/li>\n\n\n\n
    2. \u207bO\u2013S=O<\/strong><\/li>\n\n\n\n
    3. O=S=O<\/strong><\/li>\n<\/ol>\n\n\n\n

      These resonance forms share characteristics. The real structure is a hybrid<\/strong> where both S\u2013O bonds are between a single and double bond \u2014 about 1.5 bond order.<\/p>\n\n\n\n

      Thus, valid Lewis structures include:<\/p>\n\n\n\n

        \n
      • (b) O=S=O<\/strong> (complete octets, neutral formal charges)<\/li>\n\n\n\n
      • (c) :O\u2013S\u2013O<\/strong> (likely with lone pairs, possibly a resonance contributor)<\/li>\n\n\n\n
      • (d) :O\u2013S=O<\/strong> (another resonance form)<\/li>\n<\/ul>\n\n\n\n

        (a) O\u2013S\u2013O<\/strong> is not valid<\/strong> if it lacks lone pairs or formal charges, and does not satisfy the octet rule or represent the resonance.<\/p>\n\n\n\n

        Therefore, the correct Lewis Dot structures that predict SO\u2082 formulation are (b), (c), and (d)<\/strong>.<\/p>\n\n\n\n
