Which term is used to describe intermolecular forces that arise due to the polarity of two molecules?

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

Answer: (C)

Verified step by step guidance

1. Understand that intermolecular forces are forces of attraction or repulsion between neighboring molecules, different from intramolecular forces which hold atoms together within a molecule.
2. Identify that the question asks about forces arising due to the polarity of two molecules, meaning the molecules have permanent dipoles (partial positive and negative charges).
3. Recall the types of intermolecular forces: Ionic bonding (between ions), London dispersion forces (temporary induced dipoles in all molecules), dipole-dipole forces (between permanent dipoles), and hydrogen bonding (a special, stronger type of dipole-dipole involving H bonded to N, O, or F).
4. Recognize that dipole-dipole forces specifically describe attractions between the positive end of one polar molecule and the negative end of another polar molecule.
5. Conclude that the term describing intermolecular forces due to polarity of two molecules is 'dipole-dipole forces'.
