Solution Steps

Step 1: Identify Intermolecular Forces

Intermolecular forces are forces that occur between molecules. The common types of intermolecular forces include:

  • Dipole-dipole forces: These occur between polar molecules.
  • London dispersion forces: These are weak forces that result from temporary shifts in the density of electrons in electron clouds.
  • Hydrogen bonding: This is a special type of dipole-dipole interaction that occurs when hydrogen is bonded to a highly electronegative atom like nitrogen, oxygen, or fluorine.
Step 2: Identify the Intramolecular Force

An ionic bond is a type of intramolecular force, which means it occurs within a molecule, holding the atoms together. It is the electrostatic force of attraction between positively and negatively charged ions.

Step 3: Determine Which Option is Not an Intermolecular Force

Given the options:

  • Dipole-dipole force
  • London dispersion force
  • Hydrogen bonding
  • Ionic bond

The ionic bond is not an intermolecular force; it is an intramolecular force.

Final Answer

\(\boxed{\text{Ionic bond}}\)
