The correct formula of the compound whose name is hexaamminechromium(III) nitrate is<\/p>\n\n\n\n

a. Cr(NO3)6
b. Cr(NH3)6
c. Cr(NO3)36
d. [Cr(NH3)6(NO3)3]
e. Cr(NH3)63<\/p>\n\n\n\n

The correct formula for hexaamminechromium(III) nitrate is Cr(NH\u2083)\u2086\u2083, corresponding to option e<\/strong>.<\/p>\n\n\n\n

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

In coordination chemistry, the nomenclature of complex compounds follows specific conventions:<\/p>\n\n\n\n

    \n
  1. Naming the Ligands:<\/strong><\/li>\n<\/ol>\n\n\n\n
      \n
    • Neutral Ligands:<\/strong> Neutral molecules acting as ligands are named as the molecule itself, sometimes with specific names (e.g., H\u2082O as ‘aqua’, NH\u2083 as ‘ammine’).<\/li>\n\n\n\n
    • Anionic Ligands:<\/strong> Anions are named by adding an ‘o’ suffix to their root name (e.g., Cl\u207b as ‘chloro’, NO\u2082\u207b as ‘nitro’).<\/li>\n<\/ul>\n\n\n\n
        \n
      1. Naming the Central Metal Atom\/Ion:<\/strong><\/li>\n<\/ol>\n\n\n\n
          \n
        • The metal’s name is stated, followed by its oxidation state in Roman numerals within parentheses.<\/li>\n<\/ul>\n\n\n\n
            \n
          1. Order in the Formula:<\/strong><\/li>\n<\/ol>\n\n\n\n
              \n
            • The complex ion is enclosed in square brackets, with the metal symbol written first, followed by the ligands.<\/li>\n\n\n\n
            • Counterions (if any) are placed outside the brackets.<\/li>\n<\/ul>\n\n\n\n

              Applying these rules to hexaamminechromium(III) nitrate:<\/p>\n\n\n\n

                \n
              • Ligands:<\/strong> ‘Hexaammine’ indicates six ammonia (NH\u2083) molecules coordinated to the metal center.<\/li>\n\n\n\n
              • Central Metal:<\/strong> ‘Chromium(III)’ specifies a chromium ion with a +3 oxidation state.<\/li>\n\n\n\n
              • Counterion:<\/strong> ‘Nitrate’ denotes the presence of nitrate ions (NO\u2083\u207b) as counterions.<\/li>\n<\/ul>\n\n\n\n

                The complex ion [Cr(NH\u2083)\u2086]\u00b3\u207a consists of a chromium ion surrounded by six ammonia ligands, resulting in a +3 charge. To balance this charge, three nitrate ions (NO\u2083\u207b) are associated as counterions.<\/p>\n\n\n\n

                Thus, the chemical formula is Cr(NH\u2083)\u2086\u2083, aligning with option e<\/strong>.<\/p>\n\n\n\n

                This structure comprises the hexamminechromium(III) cation and three nitrate anions, ensuring electrical neutrality.<\/p>\n\n\n\n

                Understanding coordination compound nomenclature is crucial for interpreting and constructing chemical formulas accurately.<\/p>\n\n\n\n
