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

The correct answer is: B<\/strong><\/p>\n\n\n\n

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

Hydrogen peroxide (H\u2082O\u2082) consists of two hydrogen atoms and two oxygen atoms. To determine the most reasonable Lewis structure, we need to follow basic rules:<\/p>\n\n\n\n

\n\n\n\n

Step 1: Count total valence electrons<\/h3>\n\n\n\n
    \n
  • Hydrogen (H): 1 electron \u00d7 2 = 2 electrons<\/li>\n\n\n\n
  • Oxygen (O): 6 electrons \u00d7 2 = 12 electrons<\/li>\n\n\n\n
  • Total = 2 + 12 = 14 valence electrons<\/strong><\/li>\n<\/ul>\n\n\n\n
    \n\n\n\n

    Step 2: Structure requirements<\/h3>\n\n\n\n
      \n
    • Hydrogen forms only 1 bond<\/strong> and does not<\/strong> carry lone pairs in stable Lewis structures.<\/li>\n\n\n\n
    • Oxygen typically forms 2 bonds<\/strong> and has 2 lone pairs<\/strong>.<\/li>\n\n\n\n
    • In H\u2082O\u2082, the two oxygen atoms are bonded to each other<\/strong>, and each is also bonded to a hydrogen atom.<\/li>\n<\/ul>\n\n\n\n
      \n\n\n\n

      Step 3: Evaluate each choice<\/h3>\n\n\n\n
        \n
      • A<\/strong>: One oxygen has a double bond<\/strong> with the other oxygen. This creates one oxygen with only 6 electrons (violating the octet rule) and places a double bond between oxygens, which is not typical<\/strong> for hydrogen peroxide.<\/li>\n\n\n\n
      • B<\/strong>: Each hydrogen is singly bonded to an oxygen, and the two oxygens are singly bonded<\/strong> to each other. Each oxygen has two lone pairs<\/strong> and two bonds<\/strong>, fulfilling the octet rule. This is correct.<\/strong><\/li>\n\n\n\n
      • C<\/strong> and D<\/strong>: Both have double bonds between the oxygen atoms, which is incorrect for H\u2082O\u2082. These structures do not reflect the known structure and properties of the molecule.<\/li>\n<\/ul>\n\n\n\n
        \n\n\n\n

        Conclusion:<\/h3>\n\n\n\n

        Option B<\/strong> correctly represents the single bonds<\/strong> between H\u2013O and O\u2013O, and includes proper lone pairs and formal charges, matching both the experimental geometry and electronic configuration of H\u2082O\u2082. This makes B<\/strong> the most reasonable Lewis structure for hydrogen peroxide.<\/p>\n\n\n\n
