P Block Elements Question 554
$ XeO_4 $ molecule is tetrahedral having: 4 sigma bonds and no lone pairs on the central atom.
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 undergoes $ sp^{3} $ hybridization. In the fourth excited state xenon atom, there are 8 unpaired electrons. One s and three p orbitals 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.
