\[Xe{{O}_{4}}\] 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

Correct Answer: C

Solution :

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