Which of the following intermolecular forces are found in ALL molecules?

• A. Ionic forces
• B. Ion-dipole forces
• C. Hydrogen bond forces
• D. Dipole-dipole forces
• E. London dispersion forces

Answer: (E)

Verified step by step guidance

1. Understand that intermolecular forces are forces of attraction between molecules, and they vary in strength and type.
2. Recognize that London dispersion forces, also known as van der Waals forces, are the weakest type of intermolecular force and are present in all molecules, regardless of their polarity.
3. Recall that ionic forces occur between charged ions, and are not present in all molecules, only in ionic compounds.
4. Note that ion-dipole forces occur between an ion and a polar molecule, which is not applicable to all molecules.
5. Understand that hydrogen bonds and dipole-dipole forces require specific conditions, such as the presence of polar bonds or hydrogen atoms bonded to electronegative atoms, and are not found in all molecules.
