The species having bond order differnet from that in `CO` is .

Options

A. `NO^(Theta)`
B. `NO^(o+)`
C. `CN^(Theta)`
D. `N_(2)`

Answer

A

Explanation

The number of `e^(-')s` in `NO^(o+),CN^(Theta)` and `N_(2) = 14 e^(-')s` The number of `e^(-')s` in `CO =14` The bond order of `(Cunderset(larr)=O)` is 3 Therefore bond order in `NO^(o+),CN^(Theta)` and `N_(2) =3` The number of `e^(-')s` in `NO^(Theta) =16 e^(-')s` Therefore its bond order is different from `CO`
The bond order in `NO^(o+) =2.5` .
