The name of N2O5 is: Select one: a. Dinitrogen pentoxide b. Nitrogen tetroxide c. Nitrogen pentoxide d. Nitrogen oxide e. Nitrogen(V) oxide<\/p>\n\n\n\n

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

The correct answer is: a. Dinitrogen pentoxide<\/strong><\/p>\n\n\n\n

Explanation:<\/strong><\/p>\n\n\n\n

The compound N2O5 is commonly known as dinitrogen pentoxide<\/strong>. Let’s break down the name based on the compound’s structure and the rules of naming molecular compounds:<\/p>\n\n\n\n

    \n
  1. Chemical Formula<\/strong>: N2O5 indicates that there are two nitrogen (N) atoms and five oxygen (O) atoms in the molecule.<\/li>\n\n\n\n
  2. Naming Convention for Molecular Compounds<\/strong>:\n
      \n
    • In molecular (covalent) compounds, the prefix system is used to indicate the number of atoms of each element in the compound.<\/li>\n\n\n\n
    • The prefix for two<\/strong> nitrogen atoms is di<\/strong>, and for five<\/strong> oxygen atoms, it is penta<\/strong>.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Naming Nitrogen Compounds<\/strong>:\n
        \n
      • The element nitrogen is the first in the molecular formula, so it is named first, followed by oxygen.<\/li>\n\n\n\n
      • The name “pentoxide” refers to the presence of five oxygen atoms.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
      • Correct Name<\/strong>: According to these rules, N2O5<\/strong> is named dinitrogen pentoxide<\/strong>.<\/li>\n<\/ol>\n\n\n\n

        Why the Other Options Are Incorrect:<\/h3>\n\n\n\n
          \n
        • b. Nitrogen tetroxide<\/strong>: This name corresponds to the compound N2O4, not N2O5. “Tetra” refers to four oxygen atoms.<\/li>\n\n\n\n
        • c. Nitrogen pentoxide<\/strong>: While this might seem close, it lacks the proper prefix for the nitrogen part (dinitrogen for two nitrogen atoms).<\/li>\n\n\n\n
        • d. Nitrogen oxide<\/strong>: This is a general term that could refer to various nitrogen-oxygen compounds, but it does not specify the exact ratio of nitrogen to oxygen.<\/li>\n\n\n\n
        • e. Nitrogen(V) oxide<\/strong>: This is incorrect because the oxidation state of nitrogen in N2O5 is already clearly indicated by the name “dinitrogen pentoxide.”<\/li>\n<\/ul>\n\n\n\n

          Thus, the correct name is dinitrogen pentoxide<\/strong>.<\/p>\n\n\n\n
