Question

Select correct option for $O-O$ bond order.

• A. $O_{3}>O_{2}^{+}>H_{2}O_{2}>O_{2}$
• B. $O_{2}^{+}>O_{2}>O_{3}>H_{2}O_{2}$
• C. $O_{2}^{+}>O_{2}>H_{2}O_{2}>O_{3}$
• D. $O_{2}^{+}>O_{3}>O_{2}>H_{2}O_{2}$

Answer 1

Answer: (B)

$O_{3}\Rightarrow $
Bond order $=1.5$
$O_{2}^{+}\Rightarrow B.O.=\frac{N_{b} - N_{a}}{2}=\frac{10 - 5}{2}=2.5$
$H_{2}O_{2}\Rightarrow $

$\Rightarrow B.O.=1.0$
$O_{2}\Rightarrow B.O.=\frac{10 - 6}{2}=2.0$
Correct order:
(2) $\left(2\right)O_{2}^{+}>O_{2}>O_{3}>H_{2}O_{2}$
