Which of the following options represents the correct bond order?

Step-by-step solution

B . O = N b - N a 2 O 2 − ⇒ σ 1 s 2 < σ * 1 s 2 < σ 2 s 2 < σ * 2 s 2 < σ 2 p z 2 < π 2 p x 2 = π 2 p y 2 < π * 2 p x 2 = π * 2 p y 1 B.O for O 2 - = 1.5 ⇒ 10 - 7 2 = 1.5 O 2 ⇒ σ 1 s 2 < σ * 1 s 2 < σ 2 s 2 < σ * 2 s 2 < σ 2 p z 2 < π 2 p x 2 = π 2 p y 2 < π * 2 p x 1 = π * 2 p y 1 B.O for O 2 = 2.0 ⇒ 10 - 6 2 = 2 O 2 + ⇒ σ 1 s 2 < σ * 1 s 2 < σ 2 s 2 < σ * 2 s 2 < σ 2 p z 2 < π 2 p x 2 < π 2 p y 2 < π * 2 p x 1 < π * 2 p y 0 B.O for O 2 + = 2.5 ⇒ 10 - 5 2 = 2.5 As per M.O.T electronic configurations O 2 - < O 2 <
