‘What is the name of the compound with the formula CoBr3 2 What is the name of the compound with the formula FeCl3 2 What is the name of the compound with the formula CuF ?’<\/p>\n\n\n\n

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

Here are the correct names for the compounds:<\/p>\n\n\n\n

    \n
  1. CoBr\u2083<\/strong> \u2013 Cobalt(III) bromide<\/strong><\/li>\n\n\n\n
  2. FeCl\u2083<\/strong> \u2013 Iron(III) chloride<\/strong><\/li>\n\n\n\n
  3. CuF<\/strong> \u2013 Copper(I) fluoride<\/strong><\/li>\n<\/ol>\n\n\n\n
    \n\n\n\n

    Explanation <\/strong><\/h3>\n\n\n\n

    The names of these compounds follow the nomenclature rules for ionic compounds<\/strong>, specifically transition metal halides<\/strong>. Transition metals can form multiple oxidation states, so Roman numerals are used in their names to indicate the specific charge of the metal ion in the compound.<\/p>\n\n\n\n

    1. CoBr\u2083 \u2013 Cobalt(III) bromide<\/strong><\/h4>\n\n\n\n
      \n
    • Cobalt is a transition metal.<\/li>\n\n\n\n
    • Bromide (Br\u207b) has a charge of -1.<\/li>\n\n\n\n
    • There are 3 bromide ions, totaling a charge of -3.<\/li>\n\n\n\n
    • To balance this, cobalt must have a +3 charge.<\/li>\n\n\n\n
    • Therefore, the compound is cobalt(III) bromide.<\/li>\n<\/ul>\n\n\n\n

      2. FeCl\u2083 \u2013 Iron(III) chloride<\/strong><\/h4>\n\n\n\n
        \n
      • Iron (Fe) is also a transition metal.<\/li>\n\n\n\n
      • Chloride (Cl\u207b) has a -1 charge.<\/li>\n\n\n\n
      • There are 3 chloride ions, totaling -3.<\/li>\n\n\n\n
      • To balance the charges, iron must be +3.<\/li>\n\n\n\n
      • So the compound is named iron(III) chloride.<\/li>\n<\/ul>\n\n\n\n

        3. CuF \u2013 Copper(I) fluoride<\/strong><\/h4>\n\n\n\n
          \n
        • Copper can have +1 or +2 charges.<\/li>\n\n\n\n
        • Fluoride (F\u207b) is a -1 ion.<\/li>\n\n\n\n
        • Since there is only one fluoride ion, the copper must be +1 to balance the charge.<\/li>\n\n\n\n
        • Therefore, the name is copper(I) fluoride.<\/li>\n<\/ul>\n\n\n\n
          \n\n\n\n

          Key Naming Rules:<\/strong><\/h3>\n\n\n\n
            \n
          1. Cation first, then anion.<\/strong><\/li>\n\n\n\n
          2. Transition metals require Roman numerals<\/strong> to indicate their oxidation state.<\/li>\n\n\n\n
          3. Anions (like halides)<\/strong> are named by changing the ending of the element to \u201c-ide.\u201d<\/li>\n<\/ol>\n\n\n\n

            These naming conventions help chemists understand the composition and oxidation states of elements in compounds, which is essential for understanding chemical reactivity and properties.<\/p>\n\n\n\n
