What is the strength of a hydrogen bond determined by?
Interaction between the lone-pair electrons of the electronegative atom of one molecule and the hydrogen atom of another molecule
The correct answer is Interaction between the lone-pair electrons of the electronegative atom of one molecule and the hydrogen atom of another molecule.
London Dispersion Forces (Van der Waals Forces): Weak, temporary attractive forces that occur when temporary dipoles are induced in molecules due to the random movement of electrons. These forces are present in all molecules, polar or nonpolar, but are the only intermolecular forces in nonpolar molecules. Hydrogen bonding is significantly stronger than typical dipole-dipole forces and London dispersion forces, although it is weaker than covalent or ionic bonds (intramolecular forces).
