medium
Which of the following options represents the correct bond order?
A
$O_2^- > O_2 < O_2^+$
B
$O_2^- < O_2 > O_2^{+}$
C
$O_{2}^- > O_2 > O_{2}^+$
D
$O_{2}^- < O_2 < O_{2}^+$
(NEET-2015)
Solution
According to molecular orbital theory $(MOT)$
$\quad \quad \quad \quad \quad O_{2}^{-} \quad O_{2} \quad O_{2}^{+}$
No. of $e^{-} \quad 17 \quad\;\; 16 \quad \; 15$
Bond order $1.5 \quad \;\;2 \quad\;\; 2.5$
