Beta, first you count electrons in bonding and anti-bonding orbitals from the diagram, then use the formula: Bond order = (bonding electrons - anti-bonding electrons)/2. For N2 it's 3, for N2+ it becomes 2.5, and for O2- it's 1.5.
But I tell you, cramming these numbers feels like counting my moong plants before the hailstorm – you know the method, but the real test is if it survives. My rented field's bond with the earth, now that order I understand.
My grandson in Kota sent this very question last night, panicking over the board exam. I read it under the lantern, my buffalo chewing beside me, and I thought, "This city stress is the true anti-bonding force.
