Chemistry - CHEMICAL BONDING Question with Solution | TestHub

The correct order of strength of H-bond is
$\mathrm{H}\mathrm{F}>{\mathrm{H}}_2{\mathrm{O}}_2>{\mathrm{H}}_2\mathrm{O}>{\mathrm{H}}_2\mathrm{S}$
Strength of H-bonding is higher in${\mathrm{H}}_2{\mathrm{O}}_2$than${\mathrm{H}}_2\mathrm{O}$, because the amount formal negative charge on oxygen atom in case of water is more than that of${\mathrm{H}}_2{\mathrm{O}}_2$.
