In which of the following ionisation processes, the bond order has increased and the magnetic behaviour has changed?

Options

A. `C_(2) to C_(2)^(+)`
B. `NO to NO^(+)`
C. `O_(2) to O_(2)^(+)`
D. `N_(2) to N_(2)^(+)`

Answer

B

Explanation

`C_(2) to` Bond Order = 2 and diam agnetic `" " C_(2)^(+) to `Bond Order = 1.5 and param agnetic
`NO to ` Bond Order = 2.5 and paramagnetic `" "NO^(+) to `Bond Order = 3 and diamagnetic
`O_(2) to ` Bond Order = 2 and paramagnetic `" " O_(2)^(+) to ` Bond Order = 2.5 and paramagnetic
`N_(2) to ` Bond Order = 3 and diamagnetic `" " N_(2)^(+) to ` Bond Order = 2.5 and paramagnetic
