Draw the lewis structures of SO3Na and H3CO<\/p>\n\n\n\n

The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

To understand the Lewis structures of SO\u2083Na<\/strong> and H\u2083CO<\/strong>, let’s break them down:<\/p>\n\n\n\n

1. SO\u2083Na (Sodium Sulfite)<\/strong><\/h3>\n\n\n\n
    \n
  • Atoms involved:<\/strong> Sodium (Na), Sulfur (S), and Oxygen (O).<\/li>\n\n\n\n
  • Step 1: Identify the central atom.<\/strong>
    Sulfur is the central atom as it is less electronegative than oxygen and can form multiple bonds.<\/li>\n\n\n\n
  • Step 2: Count valence electrons.<\/strong><\/li>\n\n\n\n
  • Sodium (Na): 1 valence electron.<\/li>\n\n\n\n
  • Sulfur (S): 6 valence electrons.<\/li>\n\n\n\n
  • Oxygen (O): 6 valence electrons (3 oxygens in total). Total valence electrons: 1 (Na) + 6 (S) + 3\u00d76 (O) = 25 valence electrons.<\/li>\n\n\n\n
  • Step 3: Bonding.<\/strong>
    Sodium (Na) will lose its one valence electron, forming a Na\u207a ion. This leaves behind the sulfate ion (SO\u2083\u00b2\u207b), where sulfur is double-bonded to each oxygen atom.<\/li>\n\n\n\n
  • Step 4: Assign electron pairs.<\/strong><\/li>\n\n\n\n
  • Sulfur (S) will form 3 double bonds with the three oxygen atoms. This uses up 6 electrons.<\/li>\n\n\n\n
  • Each oxygen will have 2 lone pairs, each using up 2 electrons (3\u00d72 = 6).<\/li>\n\n\n\n
  • This structure leaves 2 extra electrons that will be placed on sulfur to complete its octet.<\/li>\n<\/ul>\n\n\n\n

    The Lewis structure<\/strong> of SO\u2083Na shows sulfur double-bonded to three oxygens with one oxygen forming an ionic bond with sodium. The sulfur atom has a formal charge of 0, and each oxygen has a formal charge of -1.<\/p>\n\n\n\n

    2. H\u2083CO (Formyl Group)<\/strong><\/h3>\n\n\n\n
      \n
    • Atoms involved:<\/strong> Hydrogen (H), Carbon (C), and Oxygen (O).<\/li>\n\n\n\n
    • Step 1: Identify the central atom.<\/strong>
      Carbon is the central atom as it is less electronegative than oxygen.<\/li>\n\n\n\n
    • Step 2: Count valence electrons.<\/strong><\/li>\n\n\n\n
    • Hydrogen (H): 1 valence electron (3 hydrogens = 3).<\/li>\n\n\n\n
    • Carbon (C): 4 valence electrons.<\/li>\n\n\n\n
    • Oxygen (O): 6 valence electrons. Total valence electrons: 3 (H) + 4 (C) + 6 (O) = 13 valence electrons.<\/li>\n\n\n\n
    • Step 3: Bonding.<\/strong>
      Carbon will be bonded to 3 hydrogens and double-bonded to oxygen.<\/li>\n\n\n\n
    • Step 4: Assign electron pairs.<\/strong><\/li>\n\n\n\n
    • Carbon (C) will have 3 single bonds with hydrogen and 1 double bond with oxygen.<\/li>\n\n\n\n
    • Oxygen will have 2 lone pairs.<\/li>\n<\/ul>\n\n\n\n

      The Lewis structure<\/strong> of H\u2083CO shows carbon bonded to three hydrogen atoms and double-bonded to oxygen. The oxygen atom has 2 lone pairs.<\/p>\n\n\n\n

      Conclusion:<\/h3>\n\n\n\n
        \n
      • SO\u2083Na<\/strong>: Sulfur is double-bonded to three oxygens, with one oxygen ionically bonded to sodium.<\/li>\n\n\n\n
      • H\u2083CO<\/strong>: Carbon is single-bonded to three hydrogens and double-bonded to oxygen.<\/li>\n<\/ul>\n\n\n\n
