Question

The correct order of bond length of $O-O$ in $O_2,H_2{O}_2,O_3$ is:

• A. $O_3>H_2{O}_2>O_2$
• B. $O_2>H_2{O}_2>O_3$
• C. $O_2>O_3>H_2{O}_2$
• D. $H_2{O}_2>O_3>O_2$

Answer 1

The correct option is D $H_2{O}_2>O_3>O_2$

The correct order of $O-O$ bond length in $O_2,H_2{O}_{2}and{O}_3$ is:
$H_2{O}_2>O_3>O_2$
The increasing bond order:
$\underset{1}{H_2{O}_2}>\underset{1.5}{O_3}>\underset{2}{O_2}$
Higher the bond order, shorter is the bond length.
