Q.
The correct order of strength of H-bond in the following compounds is
NTA AbhyasNTA Abhyas 2020Chemical Bonding and Molecular Structure
Solution:
The correct order of strength of H-bond is
$HF>H_{2}O_{2}>H_{2}O>H_{2}S$
Strength of H-bonding is higher in $H_{2}O_{2}$ than $H_{2}O$ , because the amount formal negative charge on oxygen atom in case of water is more than that of $H_{2}O_{2}$ .
