Explanation:

First Question:

The intermolecular force between a hydrogen atom of one water molecule and the oxygen atom of another is hydrogen bonding. This occurs because oxygen is highly electronegative, creating a partial positive charge on H and partial negative on O, leading to an attractive force.

Substances that dissolve in water are typically polar or ionic (like salts, sugars, some acids/bases) because water is a polar molecule, and "like dissolves like". For example, ionic compounds (e.g., NaCl) or polar covalent compounds (e.g., ethanol, glucose) dissolve in water.

Lipids are nonpolar, and water is polar. Substances that do not dissolve in water (polar solvent) and are nonpolar are called hydrophobic (meaning "water - fearing").

Answer:

Hydrogen Bonding
