The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n

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

A) a nitrogen-nitrogen double bond.<\/strong><\/p>\n\n\n\n

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

The Lewis structure of ( N_2H_2 ) (diazene) reveals that the molecule consists of two nitrogen atoms connected by a double bond and each nitrogen atom bonded to one hydrogen atom. Here’s how this structure is determined and why the correct answer is A<\/strong>:<\/p>\n\n\n\n

    \n
  1. Valence Electrons<\/strong>:<\/li>\n<\/ol>\n\n\n\n
      \n
    • Each nitrogen atom has 5 valence electrons (Group 15 of the periodic table).<\/li>\n\n\n\n
    • Each hydrogen atom has 1 valence electron (Group 1 of the periodic table).<\/li>\n\n\n\n
    • Total valence electrons: ( 2 \\times 5 + 2 \\times 1 = 12 ) electrons.<\/li>\n<\/ul>\n\n\n\n
        \n
      1. Skeletal Structure<\/strong>:<\/li>\n<\/ol>\n\n\n\n
          \n
        • The two nitrogen atoms are connected by a bond, and each nitrogen atom is attached to a hydrogen atom.<\/li>\n\n\n\n
        • This basic framework uses 4 electrons (2 for each ( N-H ) bond).<\/li>\n<\/ul>\n\n\n\n
            \n
          1. Distributing Remaining Electrons<\/strong>:<\/li>\n<\/ol>\n\n\n\n
              \n
            • After forming ( N-H ) bonds, 8 electrons remain.<\/li>\n\n\n\n
            • A double bond is placed between the two nitrogen atoms, using 4 electrons.<\/li>\n\n\n\n
            • Each nitrogen atom gets one lone pair of electrons, completing their octets.<\/li>\n<\/ul>\n\n\n\n
                \n
              1. Final Structure<\/strong>:<\/li>\n<\/ol>\n\n\n\n
                  \n
                • The Lewis structure shows:\n
                    \n
                  • A nitrogen-nitrogen double bond<\/strong>.<\/li>\n\n\n\n
                  • Each nitrogen atom has one nonbonding electron pair.<\/li>\n\n\n\n
                  • Each hydrogen atom is bonded to a nitrogen atom and has no lone pairs.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n
                      \n
                    1. Why Other Options Are Incorrect<\/strong>:<\/li>\n<\/ol>\n\n\n\n
                        \n
                      • ( B ): A nitrogen-nitrogen triple bond<\/strong> is incorrect as there aren\u2019t enough electrons to allow for this while maintaining single bonds with hydrogen.<\/li>\n\n\n\n
                      • ( C ): Each nitrogen has one<\/strong>, not two, nonbonding electron pairs.<\/li>\n\n\n\n
                      • ( D ): Two nonbonding pairs per nitrogen would violate the octet rule.<\/li>\n\n\n\n
                      • ( E ): Hydrogen does not have lone pairs\u2014it forms single bonds.<\/li>\n<\/ul>\n\n\n\n

                        The nitrogen-nitrogen double bond ensures the structure adheres to the octet rule and balances the electron distribution correctly.<\/p>\n","protected":false},"excerpt":{"rendered":"
