Chemical Bonding And Molecular Structure Question 445

Question: In $ XeF_2,XeF_4 $ and $ XeF_6,, $ the number of lone pairs on Xe are respectively

Options:

A) 2, 3, 1

B) 1, 2, 3

C) 4, 1, 2

D) 3, 2, 1

Show Answer

Answer:

Correct Answer: D

Solution:

  • In $ XeF_2 $ Total number of valence electrons of $ Xe=8 $ , two electrons shared with 2F atoms, 6 electrons left hence 3 lone pairs, in $ XeF_4 $ 4 shared with 4 F atoms 4 left hence 2 lone pairs; in $ XeF_6 $ 6 shared with 6 F atoms 2 left hence 1 lone pair.
