Which type of intermolecular force is present in all molecular compounds, regardless of their composition?
A
London dispersion forces
B
Dipole-dipole interactions
C
Ion-dipole interactions
D
Hydrogen bonding
Verified step by step guidance1
Understand that intermolecular forces are the forces of attraction between molecules, which influence properties like boiling point and solubility.
Recognize the different types of intermolecular forces: London dispersion forces, dipole-dipole interactions, ion-dipole interactions, and hydrogen bonding.
Know that London dispersion forces arise due to temporary fluctuations in electron distribution, creating instantaneous dipoles even in nonpolar molecules.
Realize that London dispersion forces are present in all molecular compounds because every molecule has electrons that can momentarily shift, regardless of polarity.
Conclude that while other forces like dipole-dipole interactions and hydrogen bonding require specific molecular features, London dispersion forces are universal among molecular compounds.
