Give the name for P4O10. – phosphorus (IV) oxide – tetraphosphorus decoxide – diphosphorus pentoxide – phosphorus oxide – phosphorus (II) oxide<\/p>\n\n\n\n

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

The correct name for P4O10 is tetraphosphorus decoxide<\/strong>.<\/p>\n\n\n\n

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

The naming of molecular compounds follows specific conventions set by the International Union of Pure and Applied Chemistry (IUPAC), which rely on the number of atoms of each element in the compound.<\/p>\n\n\n\n

    \n
  1. Prefix for the number of atoms<\/strong>:\n
      \n
    • “Tetraphosphorus” refers to four phosphorus (P) atoms, as indicated by the prefix tetra-<\/strong>.<\/li>\n\n\n\n
    • “Deca-” is used to indicate ten oxygen (O) atoms.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Oxide<\/strong>:\n
        \n
      • The suffix -oxide<\/strong> is used to indicate that the compound contains oxygen atoms bonded to another element (in this case, phosphorus).<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n

        The molecular formula for the compound is P4O10<\/strong>, meaning there are four phosphorus atoms and ten oxygen atoms. The IUPAC naming system uses tetra-<\/strong> for the four phosphorus atoms and deca-<\/strong> for the ten oxygen atoms, resulting in tetraphosphorus decoxide<\/strong>.<\/p>\n\n\n\n

        Why the other options are incorrect:<\/h3>\n\n\n\n
          \n
        • Phosphorus (IV) oxide<\/strong>: This name refers to a compound where phosphorus has an oxidation state of +4, which is more typical of P2O5 (diphosphorus pentoxide), not P4O10. The oxidation state of phosphorus in P4O10 can be viewed as +5 on average.<\/li>\n\n\n\n
        • Diphosphorus pentoxide<\/strong>: This name is for P2O5, not P4O10.<\/li>\n\n\n\n
        • Phosphorus oxide<\/strong>: This is too generic and doesn’t specify the number of oxygen atoms or the structure.<\/li>\n\n\n\n
        • Phosphorus (II) oxide<\/strong>: This is incorrect because phosphorus in P4O10 is in the +5 oxidation state, not +2.<\/li>\n<\/ul>\n\n\n\n

          Therefore, tetraphosphorus decoxide<\/strong> is the correct and specific name for P4O10.<\/p>\n\n\n\n
