Which of the following statement is not true for hydrolysis of $\mathrm{XeF}_6$ ?

Which of the following statement is not true for hydrolysis of $\mathrm{XeF}_6$ ?
  1. $\mathrm{XeOF}_4$ is formed.
  2. $\mathrm{XeO}_2 \mathrm{~F}_2$ is formed.
  3. It is a redox reaction.
  4. $\mathrm{XeO}_3$ is formed.

Solution

(c) : Hydrolysis of $\mathrm{XeF}_6$ is not a redox reaction. $\mathrm{XeF}_6$ reacts violently with water, but slow hydrolysis by atmospheric moisture gives highly explosive solid, $\mathrm{XeO}_3$. $\mathrm{XeF}_{6(s)}+3 \mathrm{H}_2 \mathrm{O}_{(l)} \longrightarrow \mathrm{XeO}_{3(s)}+6 \mathrm{HF}_{(a q)}$ Partial hydrolysis of $\mathrm{XeF}_6$ yields $\mathrm{XeOF}_4$ and $\begin{aligned} & \mathrm{XeO}_2 \mathrm{~F}_2 \\ & \mathrm{XeF}_6+\mathrm{H}_2 \mathrm{O} \longrightarrow \mathrm{XeOF}_4+2 \mathrm{HF} \\ & \mathrm{XeF}_6+2 \mathrm{H}_2 \mathrm{O} \longrightarrow \mathrm{XeO}_2 \mathrm{~F}_2+4 \mathrm{HF} \end{aligned}$
