Arrange the following molecules according to decreasing order of their $\mathrm{O}-\mathrm{O}$ bond lengths.

Question

Aicharya · Accepted Answer

$\mathrm{H}_2 \mathrm{O}_2$ has only single bond with bond length $1.41 Å$, $\mathrm{O}_2$ has double bond with bond length $1.33 Å$. $\mathrm{O}_3$ has a partial double bond due to resonance of lone pairs of electrons.

So, correct order is $\mathrm{H}_2 \mathrm{O}_2>\mathrm{O}_3>\mathrm{O}_2$

Arrange the following molecules according to decreasing order of their $\mathrm{O}-\mathrm{O}$ bond lengths.
