homonuclear dianions contain atoms of the same element and an overall charge of . some dianions are stable enough to exist in compounds, while others are unstable and have only been detected in the gas phase. the bond order of the molecular ion b2 2- is

Respuesta :

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.
