The correct sequence of bond order is

Step-by-step solution

According to molecular orbital theory Bond order = ( number   of   e -   in   bonding   molecular   orbital )   - ( number   of   e -   in   Anti   bonding   Molecular   orbital ) 2 Molecular electronic configuration :- O 2 + = σ 1 s 2 < σ * 1 s 2 < σ 2 s 2 < σ * 2 s 2 < σ 2 px 2 < π 2 p y 2 = π 2 p z 2 < π * 2 p y 1 = π * 2 p z 0 O 2 = σ 1 s 2 < σ * 1 s 2 < &#
