Question
Which of the species have same bond order and paramagnetic? Give reason.

$\text{N}_2,\text{F}^+_2,\text{N}^-_2,\text{O}^-_2$

✓

Answer

$\text{F}^+_2$ and $\text{O}^-_2$ have same bond order, i.e. $\frac32$ because these are isoelectronic $\text{F}^+_2$ and $\text{O}^-_2$ are paramagnetic due to presence of unpaired electrons.
