Which type of intermolecular attractive force is generally considered the strongest?

• A. Hydrogen bonding
• B. London dispersion forces
• C. Ion-induced dipole forces
• D. Dipole-dipole interactions

Answer: (A)

Verified step by step guidance

1. Understand that intermolecular forces are attractions between molecules that affect physical properties like boiling and melting points.
2. Identify the types of intermolecular forces listed: London dispersion forces, ion-induced dipole forces, dipole-dipole interactions, and hydrogen bonding.
3. Recall that London dispersion forces are the weakest and arise from temporary fluctuations in electron distribution.
4. Recognize that dipole-dipole interactions occur between polar molecules but are generally weaker than hydrogen bonds.
5. Know that hydrogen bonding is a special, strong type of dipole-dipole interaction that occurs when hydrogen is bonded to highly electronegative atoms like N, O, or F, making it the strongest among the options given.
