In which of the following processes, the bond order has increased and paramagnetic character has changed to diamagnetic ?

Options

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

Answer

A

Explanation

Magentic nature
`NOrarrNO^(+)B.O rArr 2.5 rarr3" Paramagnetic "rarr"Diamagnetic"`
`{:(N_(2)rarrN_(2)^(+)" B.O. "rArr3rarr2.5),(O_(2)rarrO_(2)^(2-)" B.O. "2rarr1):}]B.O.darr`
`O_(2)rarrO_(2)^(+)" B.O. "2rarr2.5" Paramagnetic"rarr"Paramagnetic"`
`"So, "NOrarrNO^(+)` is correct answer
