C
Van der Waals forces
D
Ionic bonding
Verified step by step guidance
1
Understand the nature of water molecules: Water (H₂O) is a polar molecule, meaning it has a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom.
Identify the types of interactions: Covalent bonding involves sharing electrons between atoms, ionic bonding involves transfer of electrons, Van der Waals forces are weak interactions between molecules, and hydrogen bonding is a specific type of dipole-dipole interaction.
Recognize the role of hydrogen bonding: In water, the partial positive charge on the hydrogen atom of one molecule is attracted to the partial negative charge on the oxygen atom of another molecule, forming a hydrogen bond.
Compare the strength and nature of interactions: Hydrogen bonds are stronger than Van der Waals forces but weaker than covalent and ionic bonds, making them the most likely interaction between water molecules.
Conclude that hydrogen bonding is the most likely interaction between two water molecules due to the polarity and structure of water, facilitating this specific type of intermolecular force.
