P-Block Elements Ques 637

Question: $ XeO_4 $ molecule is tetrahedral having:

Options:

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

Show Answer

Answer:

Correct Answer: C

Solution:

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 $ \sigma $ 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.
