Multiple Choice
Which type of intermolecular force is most commonly associated with compounds that have the lowest melting points?
A
Hydrogen bonding
B
Ionic bonding
C
London dispersion forces
D
Dipole-dipole interactions
Verified step by step guidance1
Understand that melting point is influenced by the strength of intermolecular forces: stronger forces generally lead to higher melting points.
Review the types of intermolecular forces: hydrogen bonding, ionic bonding, dipole-dipole interactions, and London dispersion forces.
Recognize that ionic bonding is not an intermolecular force but a strong ionic bond within a lattice, usually resulting in very high melting points.
Compare the relative strengths of intermolecular forces: hydrogen bonding and dipole-dipole interactions are stronger than London dispersion forces.
Conclude that compounds with the lowest melting points typically have only London dispersion forces, which are the weakest type of intermolecular force.
