A) 7
B) 8
C) 14
D) 16
Correct Answer: C
Solution :
Configuration of \[{{O}_{2}}\]molecule is \[[\sigma {{(1s)}^{2}}{{\sigma }^{*}}{{(1s)}^{2}}\sigma {{(2s)}^{2}}\sigma *{{(2s)}^{2}}\pi {{(2{{p}_{x}})}^{2}}\pi {{(2{{p}_{y}})}^{2}}\] \[\sigma {{(2{{p}_{z}})}^{2}}{{\pi }^{*}}{{(2{{p}_{x}})}^{1}}{{\pi }^{*}}{{(2{{p}_{y}})}^{1}}]\] No. of pair are 7 so total no. of paired electrons are 14.
