A) \[{{O}_{2}}\]
B) \[{{N}_{2}}\]
C) \[He\]
D) \[N{{H}_{3}}\]
Correct Answer: A
Solution :
The electronic configuration of\[{{O}_{2}}\]molecule is as: \[{{O}_{2}}:KK{{(\sigma 2s)}^{2}}{{(\overset{*}{\mathop{\sigma }}\,2s)}^{2}}{{(\sigma 2{{p}_{z}})}^{2}}{{(\pi 2{{p}_{x}})}^{2}}{{(\pi 2{{p}_{y}})}^{2}}\] \[{{(\overset{*}{\mathop{\pi }}\,2{{p}_{x}})}^{1}}{{(\overset{*}{\mathop{\pi }}\,2{{p}_{y}})}^{1}}\] In the\[{{O}_{2}}\]molecule there are two unpaired electrons, hence it shows paramagnetic character.
