What is the Lewis dot structure for Br2CNH?<\/p>\n\n\n\n

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

The Lewis dot structure for Br2CNH<\/strong> can be drawn by following these steps:<\/p>\n\n\n\n

Step 1: Count the Valence Electrons<\/h3>\n\n\n\n
    \n
  • Br (Bromine)<\/strong> is a halogen and has 7 valence electrons. Since there are two bromine atoms, that gives a total of 14 valence electrons.<\/li>\n\n\n\n
  • C (Carbon)<\/strong> is in group 14 and has 4 valence electrons.<\/li>\n\n\n\n
  • N (Nitrogen)<\/strong> is in group 15 and has 5 valence electrons.<\/li>\n\n\n\n
  • H (Hydrogen)<\/strong> has 1 valence electron.<\/li>\n<\/ul>\n\n\n\n

    Total valence electrons:
    14 (from Br) + 4 (from C) + 5 (from N) + 1 (from H) = 24 valence electrons<\/strong>.<\/p>\n\n\n\n

    Step 2: Draw a Skeleton Structure<\/h3>\n\n\n\n

    Place the atoms in the structure, with carbon (C) as the central atom since it typically forms the most bonds. The atoms will be connected as follows: Br – C – N – H<\/strong>. Both bromine atoms are single-bonded to carbon.<\/p>\n\n\n\n

    Step 3: Distribute Electrons<\/h3>\n\n\n\n

    Each single bond between atoms represents 2 electrons. We have 3 bonds in the structure:<\/p>\n\n\n\n

      \n
    • 2 electrons for the Br – C<\/strong> bond.<\/li>\n\n\n\n
    • 2 electrons for the C – N<\/strong> bond.<\/li>\n\n\n\n
    • 2 electrons for the N – H<\/strong> bond.<\/li>\n<\/ul>\n\n\n\n

      This uses up 6 electrons (3 bonds \u00d7 2 electrons).<\/p>\n\n\n\n

      Step 4: Complete the Octet (or duet) Rule<\/h3>\n\n\n\n
        \n
      • The bromine atoms<\/strong> (Br) will each have 6 electrons left after the bonding, so place 6 electrons around each Br as lone pairs. This gives each Br a complete octet.<\/li>\n\n\n\n
      • The carbon atom<\/strong> has 2 electrons from the single bonds and needs 6 more electrons to complete its octet. These 6 electrons will come from the lone pairs around the nitrogen atom<\/strong> (N). Carbon will form a double bond<\/strong> with nitrogen, leaving nitrogen with a lone pair to satisfy its octet.<\/li>\n\n\n\n
      • The nitrogen atom<\/strong> has 2 electrons from the C-N double bond, 2 electrons from the N-H single bond, and 2 electrons from its lone pair to complete its octet.<\/li>\n\n\n\n
      • The hydrogen atom<\/strong> has only 1 bond and completes its duet.<\/li>\n<\/ul>\n\n\n\n

        Step 5: Check the Structure<\/h3>\n\n\n\n
          \n
        • Each atom should have the correct number of electrons around it: carbon has 8 electrons, nitrogen has 8 electrons, bromine has 8 electrons (from the 2 lone pairs plus 2 electrons from the bond), and hydrogen has 2 electrons.<\/li>\n\n\n\n
        • This structure should satisfy the octet rule for the atoms involved, except for hydrogen, which follows the duet rule.<\/li>\n<\/ul>\n\n\n\n

          Final Structure:<\/h3>\n\n\n\n

          This structure correctly represents Br2CNH<\/strong>, with all atoms satisfying their valence electron requirements.<\/p>\n\n\n\n
