Assuming that Hund's rule is violated, the bond order and magnetic nature of the diatomic molecule B 2 is:
Text Solution
Verified by ExpertsThe correct answer is:
A
B 2 ; total number of electrons = 10. The MOT electron configuration violating the Hund's rule will be thus : 
= 
So, bond order = 
= 1
As all electrons are paired, the molecule is diamagnetic.
