Chemical Bonding And Molecular Structure Question 318
Question: In $ XeF_2,XeF_4 $ and $ XeF_6,, $ the number of lone pairs on Xe are respectively
Options:
A) 2, 1, 3
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, 14 electrons left hence 7 lone pairs, in $ XeF_4 $ 8 shared with 4 F atoms, 12 electrons left hence 6 lone pairs; in $ XeF_6 $ 12 shared with 6 F atoms, 14 electrons left hence 7 lone pairs.
