In which of the following species does the molecular orbital configuration show a paramagnetic behavior?

In which of the following species does the molecular orbital configuration show a paramagnetic behavior?

Correct Answer: O2

Step 1: Understand what paramagnetic means. Paramagnetic substances have unpaired electrons in their molecular orbitals.
Step 2: Identify the species you are examining. In this case, we are looking at O2 (oxygen molecule).
Step 3: Determine the molecular orbital configuration of O2. The configuration is: σ2s² σ*2s² σ2p² π2p² π*2p¹ π*2p¹.
Step 4: Look for unpaired electrons in the configuration. In O2, there are two unpaired electrons in the π*2p orbitals.
Step 5: Conclude that since O2 has unpaired electrons, it exhibits paramagnetic behavior.
