MCQ
$XeF_2$ and $XeF_6$ are separately hydrolysed then;
  • A
    both give out $O_2$
  • B
    $XeF_6$ gives $O_2$ and  $XeF_2$ does not
  • ✓
    $XeF_2$ alone gives $O_2$
  • D
    Neither of them gives $HF$
✓

Answer

Correct option: C.
$XeF_2$ alone gives $O_2$
c
$\text{Xe}{{\text{F}}_{2}}+{{\text{H}}_{2}}\text{O}\xrightarrow{R.T.}\text{Xe}+2\text{HF}+\frac{1}{2}{{\text{O}}_{2}}\uparrow $

$\mathrm{XeF}_{6}+3 \mathrm{H}_2O \stackrel{\mathrm{R.T}}{\longrightarrow} \mathrm{XeO}_{3}+6 \mathrm{HF}$
