Question

Which hydrogen bond is stronger intermolecular or intramolecular?

Answer 1

Hydrogen bond:

• A hydrogen ($\mathrm{H}$) atom is covalently bound to a more electronegative atom.

Intermolecular and Intramolecular Hydrogen Bond:

• The forces that regulate interactions among molecules are known as intermolecular forces.
• An intramolecular force is any force that holds the atoms of a molecule or compound together.
• Intermolecular forces are weaker as compared to intramolecular forces, which bind a molecule together.
• Actual electron sharing takes place in an intramolecular hydrogen bond.
• Therefore, it is stronger than the intermolecular hydrogen bond.
• Intermolecular forces, which occur between unbonded atoms or molecules, are usually weaker than these forces.

Final Answer:

An intramolecular hydrogen bond is much stronger.
