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

Options

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

Answer

C

Explanation

(a) `N_(2)` : bond order 3, paramagnetic `" "N_(2)^(-)` : bond order, 2.5, paramagnetic
(b) `C_(2)` : bond order 2, diamagnetic `" "C_(2)^(+)` : bond order 1.5, paramagnetic
(c) `NO` : bond order 2.5, paramagnetic `" " NO^(+)` : bond order 3, diamagnetic
(d) `O_(2)` : bond order 2, paramagnetic `" " O_(2)^(+)` : bond order 2.5, paramagnetic
