Which of the following statement is not true for hydrolysis of XeF ₆ ?

Options

  1. AXeOF ₄ is formed.
  2. BXeO ₂ ~F ₂ is formed.
  3. CIt is a redox reaction.
  4. DXeO ₃ is formed.

Correct answer

C. It is a redox reaction.

Step-by-step solution

(c) : Hydrolysis of XeF ₆ is not a redox reaction. XeF ₆ reacts violently with water, but slow hydrolysis by atmospheric moisture gives highly explosive solid, XeO ₃ . XeF _ 6(s) +3 H ₂ O _ (l) XeO _ 3(s) +6 HF _ (a q) Partial hydrolysis of XeF ₆ yields XeOF ₄ and aligned & XeO ₂ ~F ₂ & XeF ₆+ H ₂ O XeOF ₄+2 HF & XeF ₆+2 H ₂ O XeO ₂ ~F ₂+4 HF aligned
