How is the strength of hydrogen bonding affected?

Ans: The strength of the hydrogen bond mostly depends upon the electronegativity of the interacting atoms. The greater the difference between the electronegativity of hydrogen and the acceptor, the higher the strength of the hydrogen bond. Next, the strength of the hydrogen bond also depends upon the difference in the size of the atoms. If the difference is too great, there will not be sufficient nuclei interaction, and the strength of the bond will be affected.
