The correct bond order in the following species is

A

$O_{2}^+ < O_{2}^- < O_2^{2+}$

B

$O_{2}^- < O_{2}^+ < O_2^{2+}$

C

$O_2^{2+} < O_{2}^+ < O_{2}^-$

D

$O_2^{2+} < O_{2}^- < O_{2}^+$

(NEET-2015)

Solution

According to molecular orbital theory (MOT)

$\quad \quad \quad \quad \quad O_{2}^{-} \quad O_{2}^{+} \quad O_{2}^{+2}$

No. ofe $^{-} \quad 17 \quad\;\; 15 \quad\quad 14$

Bond order $1.5 \quad \;2.5 \quad \quad 3.0$
