Question

Hydrogen Bond Energy is equal to ______.

Answer 1

Hydrogen bond energy:

• Hydrogen bonding is defined as the formation of hydrogen bonds, which are a special type of attractive intermolecular forces that arise due to the dipole-dipole interaction between a hydrogen atom that is bonded to a highly electronegative atom and another highly electronegative atom that lies next to the hydrogen atom.
• The free energy content of the hydrogen bond is between $1\mathrm{kcal}{\mathrm{mol}}^{-1}\mathrm{and}5\mathrm{kcal}{\mathrm{mol}}^{-1}$, which depends on the geometry and environment of the hydrogen bond.
• This makes it more stronger than a van der Waals interaction, but weaker than covalent or ionic bonds.

Hence, hydrogen bond energy is equal to $1\mathrm{kcal}{\mathrm{mol}}^{-1}\mathrm{and}5\mathrm{kcal}{\mathrm{mol}}^{-1}$.
