FeBr₃: Ion-Dipole Forces
Iron (III) bromide is a soluble salt in water. When dissolved it will from its ions (Fe+3 and Br-). So the strongest solute-solvent interaction between it and water is Ion-Dipole forces.
AlCl₃: ?
HF: Hydrogen Bonding
HF can interact with water producing Hydrogen Bonding.
Ethanol: Hydrogen Bonding
Presents dipole-dipole forces, hydrogen bonding and London Dispersion Forces. Dipole-dipole because of the oxygen and hydrogen bonding because of the OH.
