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) $\left(2\right)O_2^{+}>O_2>O_3>H_2{O}_2$
