Which of the following pairs of species have the same bond order ?A. `CN^(-)` and `CN^(+)`B. `O_(2)^(-)` and `CN^(-)`C. `NO_(+)` and `CN^(+)`D. `CN^(-)` and `NO_(2)^(+)`

Answer» Correct Answer - D
`NO^(+) =14e^(-)`
`sigma1s^(2),sigma1s^(**2),sigma2s^(2),sigma2s^(**2),sigma2p_(z)^(2),|[pi 2p_(x)^(2)],[pi2 p_(y)^(2)]|`
`B.O=1/2(10-4)=3`
`CN^(-)=14e^(-)B.O.=3`
`CN^(+)=12e^(-) B.O. =2`
`O_(2)^(-)=17e^(-) B.O. =1.5`
