The bond order of B₂ is 1.
Bond order is the number of bonding pairs of electrons between two atoms. In a covalent bond among atoms, an unmarried bond has a bond order of one, a double bond has a bond order of two, a triple bond has a bond order of three, and so on.
Calculation:-
for b₂ = σ1s² σ1s*² σ2s² σ1s*² π²Pₓ¹ = π²Py¹
bond order = (Nb - Na)/2
= 6 - 4 /2
= 1.
Bond order, as delivered through Linus Pauling, is described because of the difference between the number of bonds and anti-bonds. The bond order itself is the number of electron pairs between two atoms. For instance, in diatomic nitrogen N≡N, the bond order among the 2 nitrogen atoms is three.
