In which of the following ionixation 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

`N_(2) (B . O. = 3 ) to N_(2)^(+)` (B. O. = 2.5)
`C_(2) (B. O .= 2 ) to C_(2)^(2+) (B.O. = 1.5)`
`NO (KK sigma_(2)^(2) sigma_(2s)^(**2) sigma_(2p_(z))^(2) pi_(2p_(x))^(2)pi_(2p_(y))^(2)pi_(2p_(x))^(**1)`,
B . O . = 2.5 paramagnetic ) `to NO^(+)`
`(KK sigma_(2)^(2) sigma_(2s)^(**2) sigma_(2p_(z))^(2) pi_(2p_(x))^(2)pi_(2p_(y))^(2)`, B.O. = 3, diamagnetic )
`O_(2) (B.O. = 2 ` , paramagnetic) `to `
`O_(2)^(+) `(B .O. = 2. 5 paramagnetic)
