According to molecular orbital theory, which of the following statement about the magnetic character and bond order is correct reagarding `O_(2)^(+)` ?

Options

A. Paramagnetic and bond order `ltO_2`
B. Paramagnetic and bond order `gtO_2`
C. Dimagnetic and bond order `ltO_2`
D. Dimagnetic and bond order `gtO_2`

Answer

B

Explanation

Bond order = `(10-6)/2=2.0`
(Two unpaired electrons in antibonding molecular orbital)

ond order `=(10-5)/2=2.5`
(One unpaired electron in antibonding molecular orbital so it is paramagnetic).
