medium
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 $1.5 \quad \;2.5 \quad \quad 3.0$
