Question

calulate the bond order of O2^2-?​

Answer 1

Answer:

The bond order will be 3. In normal O2, there are 6 bonding electrons and 2 antibonding electrons, making the bond order 2. By removing the 2 highest electrons, which reside in antibonding orbitals, to make O2^(2+), the calculation becomes (6–0)/2 = 3.
