Which of the following ion does not exist?

Which of the following ion does not exist?

Options

  1. A[CuI4]2−\left[\mathrm{CuI}_4\right]^{2-}
  2. BVO43−\mathrm{VO}_4^{3-}
  3. CWO42−\mathrm{WO}_4^{2-}
  4. DCrO42−\mathrm{CrO}_4^{2-}

Correct answer

A. [CuI4]2−\left[\mathrm{CuI}_4\right]^{2-}

Step-by-step solution

[CuI4]2−\left[\mathrm{CuI}_4\right]^{2-} does not exist because I−\mathrm{I}^{-}being a stronger reducing agent reduces Cu2+\mathrm{Cu}^{2+} to Cu+\mathrm{Cu}^{+}. 2CuI2⟶2CuI+2 \mathrm{CuI}_2 \longrightarrow 2 \mathrm{CuI}+\mathrm{I}2_2
