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.
