Which of the following lists correctly identifies the three main types of intermolecular forces found in molecular compounds?

• A. Ionic bonding, covalent bonding, metallic bonding
• B. London dispersion forces, dipole-dipole interactions, hydrogen bonding
• C. Dipole-dipole interactions, covalent bonding, London dispersion forces
• D. Hydrogen bonding, ionic bonding, van der Waals forces

Answer: (B)

Verified step by step guidance

1. Understand that the question asks for the three main types of intermolecular forces found specifically in molecular compounds, not types of chemical bonds.
2. Recall that intermolecular forces are attractions between molecules, whereas ionic, covalent, and metallic bonding are types of intramolecular bonds holding atoms together within a molecule or compound.
3. Identify the common intermolecular forces in molecular compounds: London dispersion forces (present in all molecules), dipole-dipole interactions (between polar molecules), and hydrogen bonding (a special strong dipole-dipole interaction involving H bonded to N, O, or F).
4. Recognize that ionic bonding, covalent bonding, and metallic bonding are not intermolecular forces but rather types of chemical bonds, so options listing these are incorrect for this question.
5. Conclude that the correct list of intermolecular forces in molecular compounds is: London dispersion forces, dipole-dipole interactions, and hydrogen bonding.
