Question

$XeO_4$ molecule is tetrahedral having :

• A. Two $p\pi - d\pi$ bonds
• B. One $p\pi - d\pi$ bonds
• C. Four $p\pi - d\pi$ bonds
• D. Three $p\pi - d\pi$ bonds

Answer 1

Answer: (C)

Xenon undergo $sp^3$ hybridization.
In the fourth excited state xenon atom, has 8 unpaired electrons
One $s$ and three $p$ orbital undergo $sp^3$ hybridization. Four $sp^3$ hybrid orbitals form four a bonds with oxygen atoms. They are $\sigma sp^{3}-p$. Four $p\pi - d\pi$ bonds are also formed with oxygen atoms by the unpaired electrons.
