Question

The correct order of the $O - O$ bond length in $O _{2}, H _{2} O$ and $O _{3}$ is:

• A. $H _{2} O _{2}> O _{3}> O _{2}$
• B. $O _{2}> H _{2} O _{2}> O _{3}$
• C. $O _{3}> H _{2} O _{2}> O _{2}$
• D. $O _{2}> O _{3}> H _{2} O _{2}$

Answer 1

Answer: (A)

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 is $H _{2} O _{2}(1)< O _{3}(1.5)< O _{2}(2)$.
Higher is the bond order, lower is the bond length.
