Which of the following species are isoelectronic with `N_(2)` molecule?

Options

A. `O_(2)^(+),O_(2)^(-)` and `CO^(+)`
B. `CO,CN^(-)` and `NO^(+)`
C. `CO,CN^(+)` and `NO^(-)`
D. `CO^(+),NO` and `O_(2)^(2-)`

Answer

2

Explanation

Isoelectronic species possess the same ekectronic configuaration because they consist of same total number of electrons. The `N_(2)` molecules `(14 e^(-)s)` is isoelectronic with `CO, CN^(-)` and `NO^(+)`
