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 $H_{2}O_{2}$ .

Solution
