Weak forces between molecules?

• A. Covalent Bond
• B. Intermolecular Forces
• C. Hydrogen Bond
• D. Ionic Bond

Answer: (B)

Intermolecular forces are the weak attractions that act between separate molecules. They’re responsible for many everyday properties of substances—things like boiling and melting points, viscosity, and surface tension. These forces include London dispersion forces, dipole-dipole interactions, and hydrogen bonds. Among the options, the broad term that describes all the weak forces between molecules is intermolecular forces. Covalent bonds and ionic bonds are much stronger and act within a molecule or lattice, not between separate molecules. Hydrogen bonding is a specific type of intermolecular force, but the question targets the general category.
