Chemistry - CHEMICAL BONDING Question with Solution | TestHub

The bond Length decreases with increase of bond order which is the multiplicity of bond. If $\mathrm{BO}$ is 1 its a single bond; 2 for double bond and 3 for triple bond.The bond length of $\mathrm{O}-\mathrm{O}$ in ${\mathrm{H}}_2{\mathrm{O}}_2$ is 147.5pm, in ${\mathrm{O}}_3$ is $128\mathrm{pm}$ and in ${\mathrm{O}}_2$ it is $121\mathrm{pm}$.
