AXE Description of the Bromite ((\\text{BrO}_2^-)) Anion<\/h3>\n\n\n\n

The AXE notation<\/strong> is a system used in VSEPR (Valence Shell Electron Pair Repulsion) theory to describe molecular geometry. In this notation:<\/p>\n\n\n\n

    \n
  • A<\/strong> represents the central atom.<\/li>\n\n\n\n
  • X<\/strong> represents the number of bonded atoms.<\/li>\n\n\n\n
  • E<\/strong> represents the number of lone pairs on the central atom.<\/li>\n<\/ul>\n\n\n\n

    For the bromite anion ((\\text{BrO}_2^-)):<\/p>\n\n\n\n

      \n
    1. Identify the central atom<\/strong>:<\/li>\n<\/ol>\n\n\n\n
        \n
      • The bromine (Br) atom is the central atom.<\/li>\n<\/ul>\n\n\n\n
          \n
        1. Determine the number of bonded atoms (X)<\/strong>:<\/li>\n<\/ol>\n\n\n\n
            \n
          • Bromine is bonded to two oxygen atoms.<\/li>\n<\/ul>\n\n\n\n
              \n
            1. Determine the number of lone pairs on the central atom (E)<\/strong>:<\/li>\n<\/ol>\n\n\n\n
                \n
              • Bromine belongs to Group 17 (halogens), meaning it has 7 valence electrons.<\/li>\n\n\n\n
              • The two oxygen atoms each form a single bond (with one having a negative charge), utilizing 2 valence electrons from Br.<\/li>\n\n\n\n
              • The remaining 5 valence electrons on Br form two lone pairs<\/strong> and one additional electron is used for bonding.<\/li>\n\n\n\n
              • Thus, Br has two lone pairs<\/strong>.<\/li>\n<\/ul>\n\n\n\n
                  \n
                1. Write the AXE notation<\/strong>:<\/li>\n<\/ol>\n\n\n\n
                    \n
                  • A = 1<\/strong> (Bromine)<\/li>\n\n\n\n
                  • X = 2<\/strong> (Two oxygen atoms bonded)<\/li>\n\n\n\n
                  • E = 2<\/strong> (Two lone pairs)<\/li>\n\n\n\n
                  • AXE notation: AX\u2082E\u2082<\/strong><\/li>\n<\/ul>\n\n\n\n

                    Explanation of the Geometry:<\/h3>\n\n\n\n
                      \n
                    • According to VSEPR theory<\/strong>, an AX\u2082E\u2082<\/strong> molecule adopts a bent<\/strong> or V-shaped<\/strong> geometry.<\/li>\n\n\n\n
                    • The lone pairs repel the bonded oxygen atoms, forcing them into a bent configuration.<\/li>\n\n\n\n
                    • The ideal bond angle for an AX\u2082E\u2082 system is around 104-120\u00b0<\/strong>, similar to water ((\\text{H}_2\\text{O})).<\/li>\n\n\n\n
                    • The presence of lone pairs reduces the bond angle slightly due to increased electron repulsion.<\/li>\n<\/ul>\n\n\n\n

                      Conclusion:<\/h3>\n\n\n\n

                      The AXE notation of the bromite anion ((\\text{BrO}_2^-)) is AX\u2082E\u2082<\/strong>, leading to a bent molecular shape<\/strong> due to lone pair repulsions.<\/p>\n","protected":false},"excerpt":{"rendered":"
