Question

$XeF_6$ on partial hydrolysis with water produces a compound $'X'$. The same compound $'X'$ is formed when $XeF_6$ reacts with silica. The compound $'X'$ is :

• A. $XeF_2$
• B. $XeF_4$
• C. $XeOF_4$
• D. $XeO_3$

Answer 1

Answer: (C)

$XeOF_4$

Answer 2

Partial hydrolysis of $X e F _{6}$ gives $X e O F _{4}$ (compound $X$ ) $X e F _{6}+ H _{2} O \rightarrow X e O F _{4}+ 2 H F$
$XeF _{6}$ reacts with silica $SiO _{2}$ to form $XeOF _{4}$ (compound $X$ ) $2 X e F _{6}+ S i O _{2} \rightarrow 2 X e O F _{4}+ S i F _{4}$
