Question
The correct order of the $$O - O$$ bond length in $${O_2},{H_2}{O_2}$$ and $${O_3}$$ is
A.
$${O_2} > {O_3} > {H_2}{O_2}$$
B.
$${O_3} > {H_2}{O_2} > {O_2}$$
C.
$${O_2} > {H_2}{O_2} > {O_3}$$
D.
$${H_2}{O_2} > {O_3} > {O_2}$$
Answer :
$${H_2}{O_2} > {O_3} > {O_2}$$
Solution :
The bond length of $$O - O$$ in $${H_2}{O_2}$$ is $$147.5\,pm,$$ in $${O_3}$$ is $$128\,pm$$ and in $${O_2}$$ it is $$121\,pm,$$ so the correct order is $${O_2} < {O_3} < {H_2}{O_2}.$$
