The number of $p \pi-d \pi$ 'pi' bonds present in $\mathrm{XeO}_3$ and $\mathrm{XeO}_4$ molecules, respectively are

• Correct answer
  A

  3,4
• B

  4,2
• C

  2,3
• D

  3,2

Solution

Structure of $\mathrm{XeO}_3$
$\Rightarrow 3 p \pi-d \pi$ pi bonds. Structure of $\mathrm{XeO}_4$
$\Rightarrow \quad 4 p \pi-d \pi$ bonds.

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