According to MO theory the bond orders for O 2 2 - , CO and NO + respectively, are

Step-by-step solution

(i) Molecular orbital configuration of O 2 2 - is KK   ( σ 2 s ) 2   ( σ * 2 s ) 2   𝜋 ( 2 p x ) 2   𝜋 ( 2 p y ) 2   ( σ 2 p z ) 2   𝜋 * ( 2 p x ) 2   𝜋 * ( 2 p y ) 2 Bond order = 1 2   ( N b   -   N a ) = 1 2   8   -   6   =   1 (ii) Molecular orbital configuration of CO is KK   ( σ 2 s ) 2   ( σ * 2 s ) 2   𝜋 ( 2 p x ) 2   𝜋 ( 2 p y ) 2   ( &#
