Question

Which of the following statement is not true for hydrolysis of $XeF_6$ ?

• A. $XeOF_4$ is formed
• B. $XeO_2F_2$ is formed
• C. It is a redox reaction
• D. $XeO_3$ is formed

Answer 1

The Correct Option is C

Hydrolysis of $Xe F _{6}$ is not a redox reaction. $Xe F _{6}$ reacts violently with water, but slow hydrolysis by atmospheric moisture gives highly explosive solid, $XeO _{3}$ $XeF _{6( s )}+3 H _{2} O _{( l )} \longrightarrow XeO _{3( s )}+6 HF _{( aq )}$ Partial hydrolysis of $XeF _{6}$ yields $XeOF _{4}$ and $XeO _{2} F _{2}$. $XeF _{6}+ H _{2} O \longrightarrow XeOF _{4}+2 HF$ $XeF _{6}+2 H _{2} O \longrightarrow XeO _{2} F _{2}+4 HF$
