Chemical Bonding And Molecular Structure Question 64
Question: The number of electrons that are paired in oxygen molecule is
Options:
A) 7
B) 8
C) 14
D) 16
Show Answer
Answer:
Correct Answer: C
Solution:
Configuration of $ O_2 $ molecule is $ [\sigma {{(1s)}^{2}}{{\sigma }^{*}}{{(1s)}^{2}}\sigma {{(2s)}^{2}}\sigma *{{(2s)}^{2}}\pi {{(2p_{x})}^{2}}\pi {{(2p_{y})}^{2}} $
$ \sigma {{(2p_{z})}^{2}}{{\pi }^{*}}{{(2p_{x})}^{1}}{{\pi }^{*}}{{(2p_{y})}^{1}}] $
No. of pair are 7 so total no. of paired electrons are 14.
