Is B2 diamagnetic or paramagnetic? Why?
Understand the Problem
The question is asking whether the molecule B2 is diamagnetic or paramagnetic and requires an explanation for the classification based on its electronic configuration.
Answer
B2 is paramagnetic.
B2 is paramagnetic because it has two unpaired electrons, one in each of its π2p orbitals.
Answer for screen readers
B2 is paramagnetic because it has two unpaired electrons, one in each of its π2p orbitals.
More Information
B2 gas has 10 electrons which, according to molecular orbital theory, are distributed in such a way that it results in two unpaired electrons in the π2p orbitals, making it paramagnetic.
Tips
Ensure to correctly apply the molecular orbital theory and count the electrons properly in each molecular orbital to avoid mistakes.
