Xenon (VI) fluoride on complete hydrolysis gives an oxide of xenon ' $O$ '. The total number of $\sigma$ and $\pi$ bonds in ' $\mathrm{O}^{\prime}$ ' is

• A

  2
• B

  4
• Correct answer
  C

  6
• D

  8

Solution

$\begin{aligned} &\begin{aligned} & \mathrm{XeF}_6+2 \mathrm{H}_2 \mathrm{O} \rightarrow \mathrm{XeO}_2 \mathrm{~F}_2 \\ & \sigma \text {-bond }=4 \\ & \pi \text {-bond }=2 \end{aligned}\\ &\text { Total sigma & } \pi \text { bond }=6 \end{aligned}$

Hence, the correct answer is option: 'C'.
