Which of the following species contain an element in an oxidation state that is not a whole number?

Options

  1. AVO ₄³⁻
  2. BMn ₂ O ₃
  3. CS ₄ O ₆²⁻
  4. DCl ₂ O ₇

Correct answer

C. S ₄ O ₆²⁻

Step-by-step solution

In S ₄ O ₆ ²⁻ , let ' x ' be the oxidation number of S . Thus, the element X may be bromine. aligned 4 x-12 & =-2 x & = 10 4 =2.5 aligned
