The name of the compound SO
is sodium trioxide sulfur trioxide sulfur (III) oxide sulfur (VI) oxide<\/p>\n\n\n\n

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

The correct name of the compound SO\u2083<\/strong> is sulfur trioxide<\/strong>.<\/p>\n\n\n\n

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

The compound SO\u2083<\/strong> is made up of sulfur and oxygen. In naming chemical compounds, especially oxides, the rules of nomenclature for molecular (covalent) compounds are applied. These rules involve using prefixes to indicate the number of atoms of each element and the root of the element’s name.<\/p>\n\n\n\n

Here\u2019s how the name sulfur trioxide<\/strong> is derived:<\/p>\n\n\n\n

    \n
  1. Element Name<\/strong>: The first element in the compound, sulfur, is named as it is because sulfur\u2019s symbol is S<\/strong>.<\/li>\n\n\n\n
  2. Oxide<\/strong>: The second part of the compound is oxide<\/strong> because it contains oxygen (O). The suffix -ide<\/strong> is used when the compound is formed from oxygen and another element.<\/li>\n\n\n\n
  3. Prefix for the Number of Oxygen Atoms<\/strong>: In SO\u2083<\/strong>, there are 3 oxygen atoms. The prefix “tri-“<\/strong> is used to represent the number 3. Therefore, the oxygen part becomes trioxide<\/strong>.<\/li>\n<\/ol>\n\n\n\n

    Combining these two parts, we get sulfur trioxide<\/strong>.<\/p>\n\n\n\n

    Why Not the Other Names?<\/h3>\n\n\n\n
      \n
    • Sodium Trioxide<\/strong>: This would imply that sodium (Na) is present in the compound, which is not the case here.<\/li>\n\n\n\n
    • Sulfur (III) Oxide<\/strong>: This name suggests that sulfur is in the +3 oxidation state. However, sulfur in SO\u2083<\/strong> is in the +6 oxidation state, not +3.<\/li>\n\n\n\n
    • Sulfur (VI) Oxide<\/strong>: This name is technically correct in terms of oxidation state, as sulfur is in the +6 oxidation state in SO\u2083<\/strong>. However, in the nomenclature rules for molecular compounds, we usually use simple prefixes rather than oxidation states. Hence, sulfur trioxide<\/strong> is more commonly used.<\/li>\n<\/ul>\n\n\n\n

      Thus, the correct and most commonly used name for SO\u2083<\/strong> is sulfur trioxide<\/strong>.<\/p>\n\n\n\n
