In which of the following ionization processes, the bond order has increased and the magnetic character has changed ?

Answer»

`NO to NO^(+)`
`O_(2)to O_(2)^(+)`
`N_(2)to N_(2)^(+)`
`C_(2)to C_(2)^(+)`

Solution :(A) NO (B.O. = 2.5, PARAMAGNETIC)
`RARR NO^(+)`(B.O. = 3, diamagnetic)
(B) `O_(2)` (B.O. = 2, paramagnetic)
`rarr O_(2)^(+)` (B.O. = 2.5, paramagnetic)
(C ) `N_(2)`(B.O. = 3, diamagnetic)
`rarr N_(2)^(+)`(B.O. = 2.5, paramagnetic)
(D)`C_(2)`(B.O. = 2, diamagnetic)
`rarr C_(2)^(+)`(B.O. = 1.5,paramagnetic)
Correct ANSWER is (A).
