Chemical Bonding And Molecular Structure Question 220
Question: The paramagnetic molecule at ground state among the following is
Options:
A) $ H_2 $
B) $ O_2 $
C) $ N_2 $
D) $ CO $
Show Answer
Answer:
Correct Answer: B
Solution:
$ O_2\to $ $ \sigma 1s^{2},{{\sigma }^{*}}1s^{2},\sigma 2s^{2},{{\sigma }^{*}}2s^{2},\pi 2p_x^{2}\ \begin{matrix} \pi 2p_y^{2} \\ {} \\ \pi 2p_z^{2} \\ \end{matrix} . \begin{matrix} {{\pi }^{*}}2p_y^{1} \\ {} \\ {{\pi }^{*}}2p_z^{1} \\ \end{matrix} .\ $
So two unpaired electrons are found in $ O_2 $ at ground state by which it shows paramagnetism.
