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.
