Q. Which of the following species contains equal number of $\sigma$ and $\pi$-bonds?
Chemical Bonding and Molecular Structure
Solution:
$XeO _{4}$ contain equal number of $\sigma$ and $\pi$-bonds. Number of $\sigma$ and $\pi$-bonds present in species are as follows:
Structure
$\sigma$ and $\pi$-bonds
a
$\sigma$ - bond-4 $\pi$ - bond-1
b
$\sigma-$ bond-4 $\pi$ - bond-4
c
$\sigma-$ bond-3 $\pi$ - bond-4
d
$\sigma$ - bond- 6 $\pi$ - bond-4
