LewisStructure3. In the Lewis structure of CBr
, the C atom ___<\/em><\/strong><\/em><\/strong> has two double bonds only has four single bonds only has two single bonds, and one double bond only has three single bonds and one lone pair only<\/p>\n\n\n\n

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

The correct answer is: has two single bonds, and one double bond only.<\/strong><\/p>\n\n\n\n

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

In the Lewis structure of CBr<\/strong>, we’re considering a molecule where carbon (C) is bonded to bromine (Br) atoms. However, it\u2019s important to note that CBr is not a typical diatomic molecule. Instead, it may refer to CBr4 (carbon tetrabromide)<\/strong> or just be part of a larger molecule with multiple bonds. Let’s assume you meant CBr4<\/strong>, which is carbon tetrabromide.<\/p>\n\n\n\n

Here\u2019s a breakdown of how the Lewis structure works:<\/p>\n\n\n\n

    \n
  1. Carbon’s Valence Electrons<\/strong>: Carbon has 4 valence electrons.<\/li>\n\n\n\n
  2. Bromine’s Valence Electrons<\/strong>: Each bromine atom has 7 valence electrons. In CBr4<\/strong>, there are four bromine atoms.<\/li>\n<\/ol>\n\n\n\n

    In the Lewis structure of CBr4<\/strong>:<\/p>\n\n\n\n

      \n
    • Carbon (C) forms four single bonds<\/strong> with four bromine atoms.<\/li>\n\n\n\n
    • Carbon doesn\u2019t form double bonds with bromine because bromine, being a halogen, typically forms only single bonds due to its 7 valence electrons, completing its octet with one bond.<\/li>\n\n\n\n
    • Bromine atoms can have lone pairs, but carbon does not require double bonds because it can fulfill its octet by making four single bonds.<\/li>\n<\/ul>\n\n\n\n

      Why the other options are incorrect:<\/h3>\n\n\n\n
        \n
      • “Has two double bonds”<\/strong>: This would imply that carbon is bonding with multiple atoms using double bonds, but carbon in CBr4 only forms single bonds with bromine.<\/li>\n\n\n\n
      • “Has four single bonds only”<\/strong>: This is the correct structure, where carbon forms four single bonds with the bromine atoms, ensuring each atom completes its valence shell.<\/li>\n\n\n\n
      • “Has three single bonds and one lone pair”<\/strong>: Carbon would not have a lone pair in CBr4<\/strong>, because it satisfies its octet with four bonds, not fewer.<\/li>\n<\/ul>\n\n\n\n

        Thus, CBr4<\/strong> has four single bonds<\/strong>, with carbon bonded to each bromine atom.<\/p>\n\n\n\n
