Q23 / 155 · WBJEE 2023 · Chemistry

\(\mathrm{BrF}_3\) self ionises as following

  • A
    \(2 \mathrm{BrF}_3 \rightleftharpoons \mathrm{BrF}^{+}+\mathrm{BrF}_5^{-}\)
  • Correct answer
    B
    \(2 \mathrm{BrF}_3 \rightleftharpoons \mathrm{BrF}_2^{+}+\mathrm{BrF}_4^{-}\)
  • C
    \(2 \mathrm{BrF}_3 \rightleftharpoons \mathrm{BrF}_4^{+}+\mathrm{BrF}_2^{-}\)
  • D
    \(2 \mathrm{BrF}_3 \rightleftharpoons \mathrm{BrF}_3^{+}+\mathrm{BrF}_3^{-}\)

Solution

Hint : \(2 \mathrm{BrF}_3 \rightleftharpoons \mathrm{BrF}_2^{+}+\mathrm{BrF}_4^{-}\)(Relatively more stable structures.)

Hence, the correct answer is option: 'B'.
