Which of the following intermolecular forces occurs specifically between polar molecules?

• A. Dipole-dipole forces
• B. Ionic bonding
• C. Hydrogen bonding
• D. London dispersion forces

Answer: (A)

Verified step by step guidance

1. Understand that intermolecular forces are forces of attraction or repulsion between molecules, which influence physical properties like boiling and melting points.
2. Identify the types of intermolecular forces listed: Ionic bonding, Hydrogen bonding, London dispersion forces, and Dipole-dipole forces.
3. Recall that ionic bonding occurs between ions, not molecules, so it is not an intermolecular force between polar molecules.
4. Recognize that hydrogen bonding is a special, stronger type of dipole-dipole interaction that occurs only when hydrogen is bonded to highly electronegative atoms like N, O, or F.
5. Conclude that dipole-dipole forces are the general intermolecular forces that occur specifically between polar molecules due to the attraction between their positive and negative ends.
