Chemical Bonding And Molecular Structure Question 354

Question: The paramagnetic property of the oxygen molecule due to the presence of unpaired electorns present in [Kerala PMT 2004]

Options:

A) $ {{(\sigma 2p_{x})}^{1}} $ and $ {{({{\sigma }^{*}}2p_{x})}^{1}} $

B) $ {{(\sigma 2p_{x})}^{1}} $ and $ {{(\pi 2p_{y})}^{1}} $

C) $ {{(\pi *2p_{y})}^{1}} $ and $ {{(\pi *2p_{z})}^{1}} $

D) $ {{(\pi *2p_{y})}^{1}} $ and $ {{(\pi 2p_{y})}^{1}} $

E) $ {{(\pi *2p_{z})}^{1}} $ and $ {{(\pi 2p_{z})}^{1}} $

Show Answer

Answer:

Correct Answer: C

Solution:

The paramagnetic property in oxygen came through unpaired electron which can be explained by molecular orbital theory. So 2 unpaired of electron present in $ \pi \ 2p_y^{*}\ and\ \pi \ 2p_z^{*} $ .
