Which is the strongest intermolecular force present between two molecules of water in ice?

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

Answer: (A)

Verified step by step guidance

1. Identify the types of intermolecular forces listed: hydrogen bonding, dipole-dipole interactions, London dispersion forces, and ion-dipole interactions.
2. Recall that water (H\_2O) is a polar molecule with a bent shape, which allows it to have a permanent dipole moment.
3. Understand that hydrogen bonding occurs when hydrogen is directly bonded to highly electronegative atoms like oxygen, nitrogen, or fluorine, creating a strong dipole-dipole attraction.
4. Recognize that in ice, water molecules are arranged so that hydrogen bonds form between the hydrogen atom of one molecule and the oxygen atom of another, which is stronger than regular dipole-dipole or London dispersion forces.
5. Conclude that the strongest intermolecular force between two water molecules in ice is hydrogen bonding because it is a special, stronger type of dipole-dipole interaction specific to molecules with H bonded to O, N, or F.
