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

The correct answer is nitrogen monoxide<\/strong>.<\/p>\n\n\n\n

The compound with the chemical formula NO is a binary covalent compound, meaning it is formed between two nonmetal elements, in this case, nitrogen (N) and oxygen (O). The International Union of Pure and Applied Chemistry (IUPAC) has a specific set of rules for naming these types of molecules to ensure clarity and avoid ambiguity.<\/p>\n\n\n\n

The rules for naming binary covalent compounds are as follows:<\/p>\n\n\n\n

    \n
  1. The first element in the formula is named using its full element name. In this case, it is “nitrogen”.<\/li>\n\n\n\n
  2. The second element is named by taking the root of its name and adding the suffix “-ide”. For oxygen, the name becomes “oxide”.<\/li>\n\n\n\n
  3. Greek prefixes (mono-, di-, tri-, tetra-, etc.) are used to indicate the number of atoms of each element present in the molecule.<\/li>\n<\/ol>\n\n\n\n

    Applying these rules to the formula NO:
    The first element is nitrogen. Since there is only one nitrogen atom, we start with the name “nitrogen”. A key convention in IUPAC nomenclature is that the prefix “mono-” is typically omitted for the first element. Therefore, we do not call it “mononitrogen”.<\/p>\n\n\n\n

    The second element is oxygen. There is one oxygen atom, so we must use the prefix “mono-” to indicate this quantity. Combined with the “-ide” form of oxygen, this gives us “monoxide”. Note that the “o” from “mono-” is dropped before the “o” in “oxide” for easier pronunciation.<\/p>\n\n\n\n

    Combining the names for both parts gives the full, correct IUPAC name: nitrogen monoxide<\/strong>.<\/p>\n\n\n\n

    Let’s review the other options:<\/p>\n\n\n\n

      \n
    • nitrogen oxide:<\/strong>\u00a0This is a general term that could refer to any compound containing only nitrogen and oxygen (e.g., NO, N\u2082O, NO\u2082). It is not specific enough for IUPAC standards.<\/li>\n\n\n\n
    • nitrogen oxygen:<\/strong>\u00a0This is incorrect because the second element in a binary compound must end with the “-ide” suffix.<\/li>\n\n\n\n
    • mononitrogen monoxide:<\/strong>\u00a0This is incorrect because the prefix “mono-” is not used for the first element if there is only one atom of it.<\/li>\n<\/ul>\n\n\n\n
