MCQ
$XeF_6$ 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
    $XeF_4$
  • ✓
    $XeOF_4$
  • D
    $XeO_3$
✓

Answer

Correct option: C.
$XeOF_4$
c
$Xe{F_6}\, + \,{H_2}O\, \to \mathop {XeO{F_4}\, + \,2HF}\limits_{(partial\,\,\,hydrolysis)} $

$Xe{F_6} + 2{H_2}O\, \to Xe{O_2}{F_2}+ \,4HF$

$Si{O_2}\, + \,2Xe{F_6}\, \to \mathop {\,2XeO{F_4}\, + \,Si{F_4}}\limits_{(Xenoneoxy\,\,\,tetra\,\,fluoride)} $
