The molecules that has a bond order of 1.5 according to molecular orbital theory is A) B₂⁻.
It can be calculated by substracting number of antibonding electrons from the number of bonding electrons , which is 12.
That is = 12(5−2)=1.5
It should be noted that molecular orbital theory explains that each atom tends to combine together in other to form molecular orbitals and there would be a formation of electrons in various atomic orbitals.
